Answer:
The student should weigh out 61.2g of ethanolamine [6.12 * 10]
Explanation:
In this question, we are expected to calculate the mass of ethanolamine needed to make 60.0ml of it given that the density of the ethanolamine in question is 1.02g/cm^3
Mathematically, it has been shown that mass = density * volume
Hence, by multiplying the density by the volume, we get the mass.
Now, from the question we can see that we have the values for the density and the volume. We now need to get the mass.
Since cm^3 is same as ml, we need not perform any conversion.
Hence, the needed mass is:
60 * 1.02 = 61.2g
Answer:
A. to cure human diseases
Explanation:
Kg = 3.20 x 10^4 troyounces x 0.0311kg/1 troy ounce = 995.2 kg
Answer:
12.01 g
Explanation:
Molar mass is the number of grams of a substance per mole of it.
Molar masses of elements are actually already present in the periodic table. Looking at carbon (C) on a periodic table, you'll find that its molar mass is approximately 12.01 grams.
