Calculate the formula unit mass of ZnO given the atomic mass of:
- Zn = 65 u
- Na = 23 u
- K = 39 u
- C = 12 u
- O = 16 u
Which of the following elements has the same molecular mass as its atomic mass ?
Convert 12 g of oxygen gas into moles.
Calculate the molecular mass of the following:
CuSO4·5H2O
Given atomic mass of Cu = 63·5, H = 1, O = 16, C=12, N = 14, Mg = 24, S = 32
Calculate the relative molecular masses of the following
(NH4)2 Cr2O7
[At mass : C = 12, H = 1, O = 16, Ci = 35.5, N = 14, Cu = 63.5, S = 32, K = 39, Pt = 195, Ca = 40, P = 31, Mg = 24]
From the equation
\[\ce{3Cu + 8HNO3 -> 3Cu(NO3)2 + 4H2O + 2NO}\]
(Atomic mass Cu = 64, H = 1, N = 14,O = 16)
