C.21.0 g
D.None of these

Answer 1

d

Explanation:

calcium molar mass is 40.073u~40

so 40*2.3 gives 92u

this means answer is d

pls mar as brainliest

Answer 2

92.18 g

Grams will be a larger number than moles. So, to calculate moles and MULTIPLY it by molar mass. (Hint: Think multiplication to get a larger number). 1St: Find the molar mass of Calcium (look on the periodic table): 40.08 g 2nd: Multiply the number of moles by the molar mass: 40.08 x 2.3

I hope this is help you.....
