50.0 mL of a solution of HCl is combined with 100.0 mL of 1.05M NaOH in a calorimeter. The reaction mixture is initially at 22.4

VikaD [51]

Answer:

2.1 M is the molarity of the HCl solution.

Explanation:

$HCl+NaOH\rightarrow H_2O+NaCl$

Molarity of HCl solution = $M_1=?$

Volume of HCl solution = $V_1=50.0mL$

Ionizable hydrogen ions in HCl = $n_1=1$

Molarity of NaOH solution = $M_2=1.05 M$

Volume of NaOH solution = $V_2=100.0 mL$

Ionizable hydroxide ions in NaOH = $n_2=1$

$n_1M_1V_1=n_2M_2V_2$ (neutralization )

$M_1=\frac{M_2V_2}{V_1}=\frac{1.05M\times 100.0 mL}{50.0 mL}$

$M_1=2.1 M$

2.1 M is the molarity of the HCl solution.

If you have 1.4 grams of silver (Ag), how many moles of silver do you have?

creativ13 [48]

Answer: There are 0.0129 moles of silver present in 1.4 grams of silver (Ag).

Explanation:

Given: Mass of silver = 1.4 g

Number of moles is the mass of substance divided by its molar mass.

As molar mass of silver is 107.86 g/mol. Therefore, moles of silver are calculated as follows.

$No. of moles = \frac{mass}{molar mass}\\= \frac{1.4 g}{107.86 g/mol}\\= 0.0129 mol$

Thus, we can conclude that there are 0.0129 moles of silver present in 1.4 grams of silver (Ag).

Find the molarity: 9.82 grams of lead (IV) nitrate are dissolved to make 465 mL of solution.

solmaris [256]

Molarity is moles per liter. Therefore you must covert grams->moles by dividing 9.82 by the molar mass of lead IV nitrate. Then convert mL->L. Once you have those two numbers you can plug them into the formula Molarity = mol/L.

¿Cuántos gramos de H2O habrá en 3,0115x1023 moléculas de agua?

jolli1 [7]

Answer : The weight of water is 9 g

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass and contains avogadro's number $6.023\times 10^{23}$ of particles.

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given molecules}}{\text{avogadro's number}}=\frac{3.0115\times 10^{23}}{6.023\times 10^{23}}=0.5moles
$

1 mole of water $(H_2O)$ weighs = 18 g

0.5 moles of water $(H_2O)$ weighs = $\frac{18}{1}\times 0.5=9g$

Thus the weight of water is 9 g
