Can anyone please help me find molar masses of compounds. For example Copper (ll) sulfate (CuSO4)

Answer:

Explanation:

You would have to add up the atomic masses of all the compounds in the compound, making sure you include how many molecules of each are in the compound

For example, in CuSOA we have 1 molecule of Cu and S, as 4 molecules of O

The atomic masses are as follows:

Cu = 63.55 u

S = 32.065 u

O = 15.99 units

This is how we would add it up:

(Atomic mass of Cu) + (Atomic mass of S) + 4(Atomic Mass of O)

(63.55) + (32.065) + 4(15.99)

(63.55) + (32.065) + 63.96

= 159.575 u

Molar mass is relatively simple to calculate, but you cannot do it with a periodic table, whether that be a physical one or a digital version.
in order to find the molar mass, we must find the relative atomic masses of each element that makes up the compound. With the example copper (II) sulfate. we must find the mass of Cu, S, and O.
this is where the periodic table comes in. you just look up these values!
mass Cu =63.55g
mass S = 32.06g
Mass O = 16g
The next step is to multiply the relative atomic masses by the number of that element in the compound. For instance, one mole of cu is found is this compound, one mole of s, and four moles of o. **this is found by looking at the coefficients in the formula of the compound
this would mean that the mass of oxygen in this is 16 * 4 = 64g
now, you can calculate the molar mass by adding all of the relative atomic masses together.
molar mass = molCu(mass Cu) + molS(mass S) = molO(mass O)
= 1(63.55) + 1(32.06) + 4(16) = 159.61g
this can be done for any compound following the same steps
