Mass of molecule (g) = Mr of substance over avarogado constant
Answer:
Oh come on. Look at all - then look at A.
Explanation:
I believe the answer is c
Answer:
462g
Explanation:
First, let us calculate the molar mass of Cu(CN)2. This is illustrated below:
Molar Mass of Cu(CN)2 = 63.5 + 2(12+14) = 63.5 + 2(26) = 63.5 + 52 = 115.5g/mol
Number of mole of Cu(CN)2 given from the question = 4moles
Mass = number of mole x molar Mass
Mass of Cu(CN)2 = 4 x 115.5
Mass of Cu(CN)2 = 462g
so basically a atom type contains the same number of protons. Chemical bonds put elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds. Elements can't be divided into smaller units not using large amounts of energy.
