Answer:

Mass of 2 moles of ^{238}\textrm{U} is 476.1 g

Explanation:

  • We know that number of moles of an atom is ratio of mass of the atom to it's atomic weight.
  • Atomic weight of ^{238}\textrm{U} is 238.05 g/mol
  • So, mass of 1 mol of ^{238}\textrm{U} atom is 238.05 g
  • Hence mass of 2 moles of ^{238}\textrm{U} = (2mol\times 238.05g/mol)=476.1 g
  • Hence mass of 2 moles of ^{238}\textrm{U} is 476.1 g

What is the volume of 13.21 g of ethane gas (C2H6) at STP?
yuradex [85]

The volume at STP : 9.856 L

<h3>Further explanation</h3>

Given

Mass of ethane : 13.21 g

Required

The volume at STP

Solution

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.

mol ethane(C2H6) :

= mass : molar mass

= 13.21 g : 30 g/mol

= 0.44

Volume at STP :

= 0.44 x 22.4 L

= 9.856 L

What is the mass of 3.0 x x times 10^23 atoms of neon?
Sladkaya [172]

Answer:

10.09 grams

Explanation:

First you need to know the number of moles you are dealing with.

If you know that each mole has 6.022x10²³ of something (in this case of atoms), you can divide 3x10²³ atoms of neons by 6.022x10²³ to obtain the number of moles.

You have 0.5 moles of Neon, so then by the periodic table, you see that the molar mass of neon is 20.18g/mol, so by each mole you have 20.18 grams of neon. Multiply 20.18 grams by 0.5 moles and you got 10.09 grams of Neon
