prime factorization of 3125 is

=3125=5×5×5×5×5

lcm=5⁵=3125

Step-by-step explanation:

Solution: The factors of 729 are 1, 3, 9, 27, 81, 243, 729 and factors of 712 are 1, 2, 4, 8, 89, 178, 356, 712. Therefore, the Least Common Multiple of 729 and 712 is 519048 and Highest Common Factor (HCF) of 729 and 712 is 1.

Answer:

We know, Volume of a cube of edge a =a³

.

Given, edge of the cube a=6 cm.

Therefore, the volume of the required cube is =6³

=6×6×6 = 216cm³

Answer:

18900u

Explanation:

copper carbonate formula = Cu2(OH)2CO3

Molar mass of copper carbonate = 2*63.5 + 2*(16+1) + 12 + 3*16

                                                       = 127 + 34 + 12 + 16 = 189

Moles = Mass/Molar mass

Mass = Mole * Molar mass

Mass = 189*100

Mass = 18900u

Given,

The molecule of Copper Carbonate is given.

Number of molecules = 100

The atomic mass of Cu = 63.5 u

To find,

We have to calculate the mass of 100 molecules of copper carbonate.

Solution,

The mass of 100 molecules of copper carbonate is12355 gm/mol.

We can simply calculate the mass of 100 molecules of copper carbonate by adding the molecular masses of all the atoms present in the molecule.

The molecular mass of 1 molecule of copper carbonate =  Cu + C + 3O

                                                                                            =  63.5 + 12 + 48

                                                                                            = 123.55 gm/ mol

Mass of 100 molecules of copper carbonate = 100 * 123.55

                                                                          = 12355 gm/mol

Hence, the mass of 100 molecules of copper carbonate is 12355 gm/mol.
