Question

When Jeff's blood was tested, the chloride level was 0.45 g/dL.

b. According to Table 9.6, is this value above, below, or within the normal range?

Accepted Answer

Hey, everyone. A patient's blood potassium level was measured as 0. g per de liter. If the normal range is 3.5 to 5.5 milli equivalents per liter is the value above the normal range of potassium in the blood based on our given units. For the normal range being in milli equivalents per liter. We're going to need to utilize stoic geometry to convert from our given potassium blood range and grams per dust liter to moles per liter and then from moles per liter to milli equivalents per liter. So we're going to utilize stogie. We need to make note of our molecular weight of potassium from our periodic table, which is 39.10 g per mole. And we're also going to need to recognize our unit of equivalence in which for one mole of our potassium plus one ion based on that plus one charge, we would say we have one equivalent of potassium. So now with all of these notes written down, let's begin with our conversion of our grams per dust liter to moles per liter. We have 0.0 or rather just 0.25 g per dus liter of potassium in our blood. Meaning we're going to multiply by a conversion factor to cancel out dust liters in the num and get to liters in our denominator. Recall that our prefix desi tells us that we have an equivalence of 10 to the negative first power of our base unit leader in the denominator canceling out deciliter. We have grams per liter in which now we will introduce our molar mass where we would note down that for 39 or we have 39.10 g of potassium per mole of potassium in the numerator, canceling out our units of. Now grams were left with moles per liter as our final units. This will now give us our blood potassium level in moles per liter equal to 0.63, 94 moles per liter of potassium in our blood or in the patient's blood rather. So now we need to interpret this in our given range of milli equivalents per liter. So taking our blood potassium level in moles per liter, 0.6394 moles per liter of potassium. We're going to multiply to cancel our unit of moles where we want moles of potassium in the nominator. And we want to get to equivalents of potassium in our numerator. We noted down above that for one mole of potassium based on that plus one charge, we have one equivalent of potassium. We can now cancel out moles of potassium and we're left with equivalent per liter, but we need milli equivalents. So we're going to need to introduce a second conversion factor which we multiply by to go from equivalent in the denominator to milli equivalents in the numerator. Recall that our prefix millie tells us that we have an equivalent of 10 to the negative third of our base unit equivalent. So canceling out our units of equivalent, we're left with milli equivalents per liter as our final units, which is what we want for our normal blood range. So, simplifying and taking our products here in our next line, we would find that our potassium blood level in milli equivalents per liter is equal to 6.4 mili equivalents per liter of potassium. So our final answer would be therefore that yes, this blood potassium level is above the normal range again because our given normal range was 3.5 to 5.5 milli equivalents. And so our final answer again is yes. So I hope that this made sense and let us know if you have any questions.
