## What is the molar mass for NaOH?

39.997 g/mol

Sodium hydroxide/Molar mass

**How can we calculate the molecular mass of NaOH?**

– The atomic weight of the sodium is 23, the atomic weight of the hydrogen is 1, and the atomic weight of the oxygen is 16. – Now we can calculate the molar mass or molecular weight of the sodium hydroxide by using the formula below. Molecular weight of the NaOH= 23 + 1 + (16) = 40.

**What is the molar mass of NaOH 40?**

The sum is 39.997 g/mol . This can be rounded to an even 40 g/mol .

### What is the mass of 2.90 1022 Formula units of NaOH?

Hence, the mass of 2.90×1022molecules 2.90 × 10 22 m o l e c u l e s of NaOH N a O H is 1.93g .

**How do you calculate NaOH?**

Step 1: Calculate the amount of sodium hydroxide in moles

- Amount of solute in mol = concentration in mol/dm 3 × volume in dm 3
- Amount of sodium hydroxide = 0.100 × 0.0250.
- = 0.00250 mol.
- The balanced equation is: NaOH(aq) + HCl(aq) → NaCl(aq) + H 2O(l)
- So the mole ratio NaOH:HCl is 1:1.

**What is the equivalent mass of NaOH?**

40 g/mol

The equivalent weight of sodium hydroxide NaOH is 40 g/mol.

## What is the mass of 2.80 1022 Formula units of NaOH?

The molar mass for NaOH N a O H is 40gmol 40 g m o l . Hence, the mass of 2.90×1022molecules 2.90 × 10 22 m o l e c u l e s of NaOH N a O H is 1.93g .

**What is the mass of 2.40 x10 22 formula units of NaOH?**

What is the mass of 2.40 ×1022 molecules of NaOH (Molar mass = 40.0 g/mol)? n(NaOH) = N(NaOH) / NA = 2.40 × 1022 / 6.02 × 1023 mol-1 = 0.0399 mol. m(NaOH) = n(NaOH) × M(NaOH) = 0.0399 mol × 40 g/mol = 1.596 g ≈ 1.60 g.

**What is the molar mass of Na2SO4 Brainly?**

Therefore, the molecular mass of Na2SO4 is 142.066 Grams/Mole.

### How many moles is 17.6 g Naoh?

17.6 grams of sodium hydroxide are equal to 0.440 moles of sodium hydroxide.
