Answer:
303u and 310u respectively.
Explanation:
Lead Sulphate is:- PbSO4
Given:- Pb = 207u, S = 32u and O = 16u
Therefore, adding the values for molar mass;
207 + 32 + 4(16) = 303u
Calcium phosphate is:- Ca3(PO4)2
Given:- Ca = 40u, P = 31u, O=16u
Therefore, adding the values for molar mass;
40(3) + 31(2) + 16(8) = 120 + 62 + 128 = 310 u
