to prepare 50.0 g of 10% NaNo3 solution you will need how many grams of solute
0.1 x 50 = ?
I'm writing this after reading your first post.
10% w/w means you want 10g solute/100 g solution; therefore, to make only 50 g total you will need just half that or 5 g.
To prepare a 10% NaNO3 solution, you will need to know the amount of solute (NaNO3) required.
Step 1: Convert the given percentage to decimal form.
10% = 10/100 = 0.1
Step 2: Calculate the mass of NaNO3 (solute) required.
Mass of solute = Percentage × Mass of solution
Mass of solute = 0.1 × 50.0 g
The mass of solute required to prepare a 10% NaNO3 solution with a total mass of 50.0 g is:
Mass of solute = 0.1 × 50.0 g = 5.0 g
Therefore, you will need 5.0 grams of solute (NaNO3) to prepare a 10% NaNO3 solution with a total mass of 50.0 grams.
To determine how many grams of solute (NaNO3) you will need to prepare a 10% solution, you first need to understand what a 10% solution means.
A 10% solution refers to the concentration of the solute in the solution. It indicates that 10 grams of the solute is present in every 100 milliliters (or 100 grams, as the density of water is approximately equal to 1 gram per milliliter) of the solution.
To calculate the amount of solute needed for a given mass of solution, follow the steps below:
1. Convert the percentage concentration to a decimal fraction. In this case, 10% is equal to 0.10.
10% = 0.10
2. Determine the mass of the solute required using the equation:
Mass of solute = (Percentage concentration) x (Mass of solution)
where
- Mass of solute is the unknown we are trying to find,
- Percentage concentration is 0.10 (from the previous step), and
- Mass of solution is 50.0 g.
Mass of solute = 0.10 x 50.0
Mass of solute = 5.0 grams
Therefore, you will need 5.0 grams of NaNO3 to prepare a 50.0 g solution with a 10% concentration.
