Answer: 0.31 moles/L

Explanation:

<u>Given:</u>

Mass of NaCl = 9 g

Volume of Solution = 0.50 L

Molarity: ?

The formula used to calculate Molarity is:

Molarity (M) = Number of moles of solute / Volume of solution in litres

<u>We know,</u>

Number of Moles = Given mass / molar mass

<u>So,</u>

Moles of HCl

= 9 g / (58.44 g/mol )

= 0.154 moles

<u>Therefore,</u>

Molarity

= 0.154 moles / 0.50 L

= 0.31 moles/L

A chemist determined by measurements that 0.030 moles of barium participated in a chemical reaction. Calculate the mass of bariu
schepotkina [342]

Answer: 4.1 g of barium precipitated.

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 6.023\times 10^{23} of particles.

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar Mass}}

Given : moles of barium = 0.030

Molar mass of barium = 137 g/mol

0.030=\frac{x}{137}

x= 4.1 g

Thus there are 4.1 g of barium that precipitated.

ozzi

The ingredient's molecules would be more free and move faster, then the phase would change to liquid from solid.

<u>Explanation</u>:

  • This task seeks to examine the knowledge of the kinetic phase and characteristics of matters.
  • Here we see the chef described that the ingredient's molecules are moving in place – solid.
  • On the advent of causing the ingredient to change phase by transferring energy into it – the ingredient's molecules would be more free and move faster, then the phase would change to liquid from solid.
