Question

How many moles are in 442.8 g of strontium carbonate (SrCO3)?

A) 1.000
B) 65 360
C) 1.500
D) 3.000

Answer 1

3 moles

Step-by-step explanation:

SrCO3

Mass = 442.8g

Molar mass = (87.6 + 12 * [16*3]) = 147.6g/mol

Number of moles = mass / molar mass

Number of moles = 442.8 / 147.6

Number of moles = 3
