Question

The molar mass of Nitric acid HNO3 is, (N= 14 amu, O=18g/mol, H= 1amu)

Select one:
a. $62 \mathrm{~g} / \mathrm{mol}$
b. $34 \mathrm{~g} / \mathrm{mol}$
c. $63.01 \mathrm{~g} / \mathrm{mol}$
d. $33 \mathrm{~g} / \mathrm{mol}$

CramX · Accepted Answer

Step 1: : Determine the molar mass of each element in HNO$_3$. The molar mass of Nitrogen (N) is given as 14 amu. The molar mass of Oxygen (O) is given as 18 g/mol. The molar mass of Hydrogen (H) is given as 1 amu. However, we need to convert the molar mass of Hydrogen from amu to g/mol to maintain consistency. We know that 1 amu is approximately equal to 1 g/mol. So, the molar mass of Hydrogen (H) is 1 g/mol. Step 2: : Calculate the molar mass of HNO$_3$. Step 3: : Simplify the calculation. Final Answer: The molar mass of Nitric acid HNO$_3$ is 69 g/mol (option c).
