The number of moles present in the FeSO4 are 0.055 mol.

<u>Explanation:</u>

  • The mass of a substance containing the same number  atoms in 12.0 g of 12C is known as mole. One mole of any substance is equal to  6.023 x 10^23. The moles of a substance can be determined by using the formula,

                 Number of moles = mass in grams / molecular mass

Given,

    mass = 8.36 g,

    molecular mass of FeSO4 = 151.908 g / mol

         number of moles = 8.36 / 151.908

                                       = 0.055 mol.

The density of aluminium is 2830 Kg/M^3. what is the density of aluminum in g/cm^3?​
postnew [5]
<h3>Answer:</h3>

2.83 g/cm³

<h3>Explanation:</h3>
  • Density of a substance is the ratio of mass of the substance to its volume.

Therefore;

  • Density is given by dividing mass of a substance by its volume.
  • It is measure in g/cubic centimeters or kg per cubic meters.

In this case;

Density of Al = 2830 Kg/m³

We are required to convert is to g/cm³

We use the relationship;

1 g/cm³ = 1000 kg/m³

Therefore;

= 2830 kg/m³ ÷ 1000 kg/m³

= 2.83 g/cm³

Hence, 2830 kg/m³ of Aluminium is equivalent to 2.83 g/cm³

Mass of water = 80 x 18
= 1440 grams

Specific heat of water = 4.186 J/gK

Heat absorbed from water = mCpΔT
= 1440 x 4.186 x (21.6 - 18.1)
= 21.1 kJ

Moles of NH₄NO₃ = 3.53 / (14 + 4 + 14 + 16 x 3)
= 0.044 mol

Heat of solution = 21.1/0.044 kJ/mol
= 480 kJ/mol
