Calculate the molecular mass of a 2.66g sample of gas at a temperature of pressure of 845torr and occupying a volume of 0.70L.
ratelena [41]

The molecular mass of a 2.66g sample of gas at a temperature of pressure of 845torr and occupying a volume of 0.70L is 84.16g/mol.

<h3>How to calculate molecular mass?</h3>

The molecular mass can be calculated by first calculating the number of moles using the following formula:

PV = nRT

Where;

  • P = pressure
  • V = volume
  • n = no of moles
  • R = gas law constant
  • T = temperature

1.112 × 0.7 = n × 0.0821 × 300

0.7784 = 24.63n

n = 0.032mol

molecular mass = 2.66g ÷ 0.032mol

molecular mass = 84.16g/mol

Therefore, the molecular mass of a 2.66g sample of gas at a temperature of pressure of 845torr and occupying a volume of 0.70L is 84.16g/mol.

Maple has a sample of graphite, which is made up of carbon atoms. She has 1.810 x 1024 atoms of carbon. What is the mass of this
Lera25 [3.4K]

Answer:

  about 36.10 g

Explanation:

The proportion of interest is ...

  mass/atoms = x/(1.810·10^24) = (12.0107 g)/(6.02214076·10^23)

Multiplying by 1.810·10^24, we find the mass of the sample to be ...

  x = 36.0991 g

The mass of the sample is about 36.10 grams (to 4 s.f.).

How much energy does cameron need to add to raise the temperature of a 0.500-kg sample of silver from 200 k to 205 k? the specif
zzz [600]

energy to raise temperature is 590 J

Given:

mass of silver sample = 0.5 kg

initial temperature = 200 k

final temperature = 205 k

specific heat of silver = 236 j/kgk

To Find:

energy to raise temperature

Solution: The heat energy required to raise the temperature of of a substance through is called its specific heat capacity.

Q = cmΔt

where c= constant of proportionality, called specific heat capacity of the body

Q = mass x specific heat x ∆t

= 0.5 x 236 x ( 205-200 )

= 590 J

So, energy to raise temperature is 590 J
