Answer:
it has six significant figures
Explanation:
Structural formula of propene
molecular formula = C₃H₆
molecular mass = 12×3+1×6 = 36+6 = 42
no. of double bond = 1
<span>molecular weight of Ca(NO3)2 --> 164
Ca=40
N=14
O=16
molecular weight of Li3PO4 --> 115.8
molecular weight of LiNO3 --> 68.9
Ca3(PO4)2 produced ---> 310.2 g/mol molecular weight
Hence the answer would be 310.2 g/mol of calcium phosphate will be produced</span>
