What is the mass, in grams, of 9.01 x 1024 molecules of methanol (CH, OH) ?
Zina [86]

Answer:

480.6 g

Explanation:

Given data:

Number of molecules of methanol = 9.01 ×10²⁴

Mass in gram = ?

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ molecules

9.01 ×10²⁴molecules ×1 mol /6.022 × 10²³ molecules

1.5 ×10¹ mol

15 mol

Mass in gram:

Mass = number of moles × molar mass

Mass = 15 mol × 32.04 g/mol

Mass = 480.6 g

When hydrated copper(II) sulfate crystals are heated, anhydrous copper(II) sulfate forms. A mass of 12.5 g of hydrated copper(II
pychu [463]

The formula of hydrated copper(II) sulfate is CuSO4.10H2O

<h3>What is the formula of the hydrated copper (ii) sulfate salt?</h3>

The formula of the hydrated copper (ii) sulfate is determined as follows:

Mass of hydrated salt = 12.5 g

Mass of anhydrous salt = 8.0 g

Mass of water = 12.5 - 8 = 4.5 g

mole ratio of water and anhydrous salt is;

4.5/18 : 8.0/159.5

0.562 : 0.05

10 : 1

Water of crystallization (n) = 10.

Therefore, the formula of hydrated copper(II) sulfate is CuSO4.10H2O

A solution contains 35 mL of 1.50M CuSO​ . What is the molarity when the new 4​ volume is 100mL
elena-s [515]

Answer:

0.525 M CuSO

Explanation:

Molarity (M) is the units mol/L. Let's figure out how many moles of CuSO we have:

35 mL = 35/1000 L = 0.035 L

0.035 L * 1.50 mol/L = 0.0525 mol CuSO

Our new volume is 100 mL, so let's first convert this to L:

100 mL = 100/1000 L = 0.100 L

To find the new molarity, divide the number of moles (0.0525 moles) by the number of liters (0.100 L):

0.0525 mol / 0.100 L = 0.525 M CuSO

Hope this helps!
