Question

Calculate the mass in grams for 0.25 mole of sulphur di oxide

Answer 1

Explanation:

$0.25 \times 64 = 16$

Number of moles= given mass/ molar mass

molar mass of SO2 = 32+16×2=64

hope it helps

I'm new here I will try to answer as much as I can so do follow me for more

Answer 2

molecular mass of So2 = 64.066 g / mol

mass of the substance = n × molar mass

mass of 0.25 mole of So2 = 32.066 u × 64.066 =

2,054.340356 g ..
