## How many moles of HCl are in 25 mL?

**0.0042 moles** of HCl in the 25 mL sample.

## How many moles of HCl are present in 35.5 mL?

No. of moles = molarity x no. of litres = 0.2 x (35.5/1000) = **0.0071 mol**.

## How many moles are in HCl?

Using periodic table you can find molar mass of HCl, which is 36.458 g/mol. This means 1 mol of HCl is 36.458 grams. So 20 g of HCl is **0.548 mol**.

## How do you calculate HCl?

**Step 3: Calculate the concentration of hydrochloric acid in mol/dm ^{3}**

- Concentration in mol/dm
^{3}= - Concentration in mol/dm
^{3}= - = 0.125 mol/dm
^{3} - Relative formula mass of HCl = 1 + 35.5 = 36.5.
- Mass = relative formula mass × amount.
- Mass of HCl = 36.5 × 0.125.
- = 4.56 g.
- So concentration = 4.56 g/dm
^{3}

## How many moles of HCl are present in the original 25.00 mL of acid?

0.0500 moles/L * . 025L = **0.00125 moles**.

## How many mL is 5grams?

Grams to mL conversions (water)

Grams to mL | Grams to mL |
---|---|

3 grams = 3 mL | 150 grams = 150 mL |

4 grams = 4 mL | 200 grams = 200 mL |

5 grams = 5 mL |
250 grams = 250 mL |

6 grams = 6 mL | 300 grams = 300 mL |

## How many moles of HCl are present in 1L of 1M HCl?

Putting the value in formula, we will get the answer **1 mol** of HCl. 1 mol of HCl present in 1M solution of 1L volume.

## How many moles of Ch₃oh are there in 150.0 mL of 0.275 M Ch₃oh?

The are ≈ **0.0428 moles** of CH₃OH in 150.0 mL of 0.285 M CH₃OH.

## What amount of HCl is present in 500ml of 0.1 N solution?

Answer: your answer is **0.05mole**.
