Molar mass of FeCl3, Co(NO3)2, C4H10O, and Cu(NO3)2? Show work.

Molar mass of FeCl₃ 162.204 g/mol

Molar mass of  C₄H₁₀O is 74.1212 g/mol

Molar mass of Cu(NO₃)₂ is 187.5594 g/mol

Step-by-step explanation:

Molar mass is also termed as molecular mass of the compound. So it is the measure of the amount of mass present in the given molecule. It can be obtained by adding the products of number of atoms with their molecular mass.

For example, in order to find the molar mass of FeCl₃, the molecular mass of Fe is noted as 55.845 g/mol and the molecular mass of Cl is noted as 35.453 g/mol.

As FeCl₃ contains one atom of Fe and 3 atoms of Cl, then the

Molar mass = (Number of Fe atoms × Molecular mass of Fe) + ( Number of Cl atoms × Molecular mass of Cl)

Molar mass of FeCl₃ = (1×55.845)+(3×35.453)=162.204 g/mol.

Similarly, the molar mass of C₄H₁₀O will be

Molar mass = (4×Mass of C) + (10×Mass of H) + (1 × Mass of O)

Molar mass = (4×12.0107)+(10×1.00784)+(1×16)=74.1212 g/mol

Then the molar mass of Cu(NO₃)₂ will be

Molar mass = (1× Mass of Cu) + (2×Mass of N)+(6×Mas of Oxygen)

Molar mass = (1×63.546)+(2×14.0067)+(6×16)

Molar mass = 187.5594 g/mol

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
