How many moles are present in a sample of HCl with a mass of 3.65g? A)3.46 moles B)0.100 moles C)2.19 10²⁴moles D)10.0 moles

Question

Quizplus · Accepted Answer

To find the number of moles in the sample, we need to use the formula: 
moles = mass/molar mass

The molar mass of HCl is 36.5 g/mol (1 H atom = 1.01 g/mol and 1 Cl atom = 35.5 g/mol).

So, moles = 3.65 g / 36.5 g/mol = 0.1 mol

Therefore, the correct answer is B) 0.100 moles.
