How many moles of copper are there in 128 grams of copper?

Answer 1

Multiply 564 grams of copper by 1 mole over the Atomic Mass of copper (represented in grams).

564 g Cu * 1 mol Cu / (atomic mass) g Cu

The atomic mass is located on the Periodic Table and represented in atomic units. The same value is used here, but with the unit as grams.

Answer 2

For this you need the atomic mass of Cu. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.

48.62 grams Cu / (63.5 grams) = .766 moles Cu

Answer 3

The no. of moles can be calculated by knowing the atomic mass of Copper(Cu) i.e. 63.5g. Now applying the formula,[ no. of moles = given mass /atomic mass ]

now put the values, [ no. of mole = 128/63.5 ] = 2 moles in 128g of Cu

Answer 4

For this you need the atomic (molecular) mass of Cu(OH)2. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. Cu(OH)2=99.5 grams

68.0 grams Cu(OH)2 / 99.5 grams = .683 moles Cu(OH)2

Answer 5

To convert from grams to moles, use this general formula:

Grams ÷ Molar mass = Moles

10.0 grams Cu ÷ 63.5 grams Cu = 0.157 moles Cu

See the related question below that details the conversion of grams to moles and moles to grams.

Answer 6

4 grams Cu ( 1mol Cu/63.35 grams ) = 0.063 mol

Answer 7

Molar mass of it is 63.5. So there are 0.02852 copper moles.

Answer 8

There are approximately 2 moles of copper in 128 grams of copper, since the molar mass of copper is 63.55 g/mol. By dividing the given mass by the molar mass, you can calculate the number of moles.
