How many grams of sucrose will be necessary to prepare 300 ml of a 5% solution of sucrose (342.0 g/mol)

5% what. weight/volume? weight/weight? volume/volume?

I assume you mean w/v since you want 300 mL of solution.
5% means 5 g sucrose/100 mL solution. You want 300 so
5g x (300/100) = 15g
So you need 15 g sucrose/300 mL solution.

Oh sweet question! Sucrose, the glammed-up party guest of the sugar world. To find out how many grams you'll need for your 5% solution, let's calculate it step by step, so we don't sugarcoat the truth!

First, we calculate the molar mass of sucrose (which is 342.0 g/mol), just to get our molecular weight game strong.

Next, we convert the 5% solution requirement into grams. This means we need 5% of the total solution to be made up of sucrose. Since we have 300 ml of solution, we multiply 300 ml by 0.05 (or 5% as a decimal) to find out how many grams of sucrose we need.

Just crunching these numbers... *drum roll please*... you'll need approximately 51.3 grams of sucrose for your sweet 300 ml solution. So, go ahead and make that solution as sweet as can be!

To determine the number of grams of sucrose needed to prepare a 5% solution, we need to use the formula:

Mass of solute = (Volume of solution in mL) × (Concentration of solution in g/mL)

First, we need to convert the volume of the solution from mL to L, as the concentration is usually given in grams per liter (g/L). 1 L = 1000 mL.

Volume of solution = 300 mL ÷ 1000 = 0.3 L

Now, we can substitute the values into the formula:

Mass of sucrose = (0.3 L) × (5 g/L) = 1.5 g

Therefore, 1.5 grams of sucrose will be necessary to prepare 300 mL of a 5% solution.

To determine the number of grams of sucrose required to prepare a 5% solution, we need to calculate the mass of sucrose needed.

The formula for calculating mass is:

Mass = Volume × Density

However, in this case, we can simplify the calculation since we know the concentration is given as a percentage.

The concentration is defined as the ratio of the mass of the solute (in this case, sucrose) to the volume of the solution. So, if we want a 5% sucrose solution, it means that 5 grams of sucrose will be dissolved in 100 ml (0.1 liters) of water.

To calculate the mass of sucrose needed for 300 ml of solution, we can set up a proportion:

5 grams x grams
--------- = ----------
100 ml 300 ml

Cross multiplying, we get:

100 ml × x grams = 5 grams × 300 ml

Now, let's solve for x grams:

x grams = (5 grams × 300 ml) / 100 ml

x grams = 1500 grams / 100 ml

Calculating further:

x grams = 15 grams

Therefore, 15 grams of sucrose will be necessary to prepare 300 ml of a 5% sucrose solution.
