2.25 g/ml at 700mmHg, 200 C. Find molar mass of gas.
Harrizon [31]

Answer:

Molar mass = 94972.745 g/mol

Explanation:

Given data:

Density = 2.25 g/ml

Pressure = 700 mmHg

Temperature = 200°C

Molar mass = ?

Solution:

Density = 2.25 g/ml (2.25×1000 = 2250 g/L)

Pressure = 700 mmHg (700/760 = 0.92 atm)

Temperature = 200°C (200+273 = 473K)

Formula:

d = PM/RT

M = dRT/P

M = 2250 g/L × 0.0821 atm.L /mol.K ×  473K / 0.92 atm

M = 87374.93 g/mol / 0.92

M = 94972.745 g/mol

If an atom has 15 protons, 14 neutrons, and 16 electrons, what is the atom's electrical charge? A. -2 B. +1 C. +3 D. -1
Amiraneli [1.4K]

The electrical charge of an atom having 15 proton, 14 neutrons and 16 electrons is -1. The correct option is D.

What is an atom?

An atom is the smallest unit of any matter which comprises of central nucleus and electrons revolving around the nucleus in definite energy shells. The atom is made up of protons, neutrons and electrons.

The electrical charge of an atom can be calculated as,

Charge of an atom = number of protons - number of electrons

Charge = 15 - 16 = -1.

The neutrons are neutral and do not contribute to the charge, the protons are positively charged and electrons are negatively charged in an atom.

Therefore, the charge of an atom with 15 protons, 14 neutrons and 16 electrons is -1. The correct answer is option D.
