Q1
If 10 grams of NaOH are dissolved in water, how many moles of NaOH are present? (Molar mass of NaOH = 40 g/mol)
0.25 moles
0.5 moles
1 mole
2.5 moles
Show Solution
Copy
To find the number of moles, use the formula: moles = mass/molar mass. Thus, 10 g / 40 g/mol = 0.25 moles.

Q
Q: If 10 grams of NaOH are dissolved in water, how many moles of NaOH are present? (Molar mass of NaOH = 40 g/mol)
Solution:
To find the number of moles, use the formula: moles = mass/molar mass. Thus, 10 g / 40 g/mol = 0.25 moles.
Steps: 6
Show Steps
Step 1: Identify the mass of NaOH you have, which is 10 grams.
Step 2: Identify the molar mass of NaOH, which is given as 40 grams per mole.
Step 3: Use the formula to calculate moles: moles = mass / molar mass.
Step 4: Substitute the values into the formula: moles = 10 grams / 40 grams per mole.
Step 5: Perform the division: 10 / 40 = 0.25.
Step 6: Conclude that there are 0.25 moles of NaOH present.
