Answer:

n=17.85 moles

Explanation:

Given mass is, m = 1.5 kg = 1500 g

The molar mass of sodium bicarbonate is, M = 84.007 g/mol

We need to find the no of moles in 1.5 kg of Sodium bicarbonate . We know that, no of moles is equal to given mass divided by molar mass.

$n=\dfrac{m}{M}\\\\n=\dfrac{1500}{84.007 }\\\\n=17.85$

<h2>So, there are 17.85 moles in 1.5 kg of Sodium bicarbonate.</h2>

In a closed system containing three different gases as shown, X2 + Y2 2XY. Choose the TWO things that MUST happen as the volume

Kitty [74]

Answer:

3) The relative concentrations of each gas must remain constant.

4)The concentration of each gas will not change.

Explanation:

For the equilibrium system:

The no. of moles of gases in each side is constant; there is 2 moles of gases at reactants side and 2 moles of gases at products side.

So, changing the volume will not affect on the equilibrium system.

<em>So, the right choice is:</em>

3) The relative concentrations of each gas must remain constant.

4)The concentration of each gas will not change.

How many grams of FeCl 3 are in 250. mL of a 0.100 M solution?

Naddika [18.5K]

Answer:

The correct answer is option B

Explanation:

$$Molarity=\frac{Weight}{Molecular \,weight} \frac{1000}{V(in \, ml)}$

Given values,

Molarity of $FeCl_3=0.100M$

Volume of solution, $V=250ml$

Molecular weight of $FeCl_3=162.2$

Substituting this values in Molarity formula, we get

$0.1=\frac{weight}{162.2} \times\frac{1000}{250} $\\$\Rightarrow 16.22=weight\times4$\\$\Rightarrow weight=\frac{16.22}{4} $\\$\therefore weight=4.06g$
