Answer:

B = A/DH – C

Explanation:

From the question given above, we obtained:

A = D • H(B + C)

Thus, we can obtain B in terms of D, H, A and C by doing the following:

A = D • H(B + C)

A = DH(B + C)

Divide both side by DH

A/DH = B + C

Subtract C from both side

A/DH – C = B + C – C

A/DH – C = B

B = A/DH – C

Calculate each of the following quantities:
aleksley [76]

The mass of 2.88 × 10²² molecules of Bi (NO₃)₃ is 678.854 grams.

<h3>What is mass?</h3>

Mass is the quantity of matter in a physical body. Mass can be calculated by dividing the molar mass by the mass of the moles of the substance.

The molar mass of Bi (NO₃)₃ is 1461.99 g/mol

The molecules here is 2.88×10²²

The number of molecules will be divided by 6.023 x 10²³

2.88×10²² /  6.023 x 10²³ = 4.781 moles

Putting the value in the equation

mole = mass/molar mass

mass = moles x molar mass

4.781  x 1461.99  = 678.854 grams

Thus, the mass of 2.88×10²² molecules of Bi (NO₃)₃ is 678.854 grams
