12.5 (g CuCO3) = [12.5 (g CuCO3) / 123.555 (g/mol CuCO3)] = 0.1012 (mol CuCO3)
0.1012 (mol CuCO3)* [1 (mol CuO) / (mol CuCO3)] = 0.1012 (mol CuO)
= [0.1012 (mol CuO) * 79.545 (g/mol CuO)] = 8.047 g CuO = 8.05 g CuO
That is exactly 1 cup.
That is approximately 1/2 cup.
1 BOU = 1.54 kg
a cup of flour is 250gm, half a cup is 125gm, and three quarters is 192.5gm and one quarter is 67.5gm. so 180gm is just under 3/4 of a cup. hope that helps
