Question

Calculate the mass of 2.8 moles of chlorous acid (HCIO). Explain the process or show your work by including all values used to determine the

answer.

Answer 1

147g

Step-by-step explanation:

The number of moles or mass a substance contains can be calculated using the formula:

Mole (mol) = Mass (g) /Molar mass (g/mol)

Based on the provided information in this question,

mole = 2.8moles, mass =?

Molar Mass of HClO

Where; H =1, Cl=35.5, O=16

1 + 35.5 + 16

= 52.5g/mol

Using mole= mass/MM

mass = mole × MM

mass = 2.8 × 52.5

mass = 147g

147g of chlorous acid (HClO)
