How many grams are in 2.3 x 10^-4 moles of ca3(po4)2

Molar mass 

Ca₃(PO₄)₂ = 310 g/mol

1 mole > 310 g
2.3x10⁻⁴ mole > ?

m = 2.3x10⁻⁴ * 310 / 1

m = 0.0713 g 

hope this helps!

Yes she is correct. the answer is completely correct

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
