## How many moles are in kmno4?

Explanation: And moles of potassium permanganate = 23.7⋅g158.03⋅g⋅mol−1 ≅16⋅mol .

## What is 50 grams in moles?

To calculate the weight of an element in grams to moles, we should know the molar mass of an element. For example, 50 grams of oxygen is equal to 3 moles.

## How many moles are in 50 grams of sodium?

Na has an atomic mass of 23 and Cl is 35.5. So the Mr(NaCl)= 23 + 35.5 = 58.5. Putting all of this into our moles equation gives us the answer: moles= 50/58.5 = 0.855 moles (3sf).

## How many moles are in 50 grams of water?

There are 3 moles of O in 50 g.

## How many grams are in 1.70 moles of KMnO4?

1.70 moles KMnO4 = 269g KMnO4 (molar mass KMnO4 = 158.0g)

## What is the mole of CO2?

Mass of 1 mole (6.023 X 1023 molecules) of CO2 is about 44g.

## How do you convert to moles?

A substance’s molar mass is calculated by multiplying its relative atomic mass by the molar mass constant (1 g/mol). The molar mass constant can be used to convert mass to moles. By multiplying a given mass by the molar mass, the amount of moles of the substance can be calculated.

## How many moles are in 50g of caco3?

Calculate the number of moles in 50g CaCO3. ∴ 50 g of CaCO3 = (1100×50) ( 1 100 × 50 ) mole = 0.5 mole.

## How many moles is 55g of NaCl?

The molecular weight of Na and Cl are 23 and 35.5 g/mol respectively. The molecular weight of NaCl = (23 +35.5) = 58.5g/mol. The moles of the sample is 23.4 moles.

## How many moles are in a CU?

The relation between molecular (formula) mass and molar mass Page 4 4 • To obtain one mole of copper atoms (6.02 x 1023 atoms), weigh out 63.55 g copper. The molar mass (M) of a substance is the mass of one mole of entities (atoms, molecules, or formula units) of the substance.

## What is the moles of oxygen?

One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.

## How many moles does cacl2 have?

The molar mass of CaCl2 is 110.98 g/mol. The conversion factor that can be used is then based on the equality that 1 mol = 110.98 g CaCl2. Dimensional analysis will allow you to calculate the mass of CaCl2 that you should measure. When you measure the mass of 333 g of CaCl2, you are measuring 3.00 moles of CaCl2.
