Question

What is the mass of 0.11 moles of sodium carbonate, Na2CO3?

Answer 1

Molar mass

• 2(23)+12+3(16)
• 106g/mol

Mass:-

• No of moles ×Molar mass
• 0.11(106)
• 11.66g

Answer 2

Answer: 11.66g

Step-by-step explanation:

Number of mole= Mass/Molar Mass

Molar Mass of Na2CO3 = (23*2)+12+(16*3)
= 106g/mol
0.11moles = Mass/(106g/mol)
Mass= 0.11*106
Mass= 11.66g
