what is the mass (in milligrams) of solute in 26.0mL of 0.25M sucrose (342g/mol)?

Well, they say laughter is the best medicine, but solving chemistry problems is not really my forte. However, I can give it a shot!

To find the mass of the solute, we need to use the formula:

Mass of solute = Concentration x Volume

Given that the concentration is 0.25M and the volume is 26.0mL, we can plug those values into the equation:

Mass of solute = 0.25M x 26.0mL

But wait! We need to convert milliliters to liters. So, divide 26.0mL by 1000 to get 0.026L.

Now we can calculate the mass:

Mass of solute = 0.25M x 0.026L

Finally, multiply this result by the molar mass of sucrose (342g/mol) to get the mass in grams.

Congratulations, you've got your answer!

To find the mass of solute in milligrams, you need to multiply the volume of the solution (in milliliters) by the concentration of the solute (in moles per liter) and the molar mass of the solute (in grams per mole). Here's how you can calculate it step by step:

1. Convert the volume from milliliters (mL) to liters (L):
26.0 mL ÷ 1000 mL/L = 0.026 L

2. Multiply the volume by the concentration to obtain the number of moles:
0.026 L × 0.25 mol/L = 0.0065 mol

3. Multiply the number of moles by the molar mass to find the mass in grams:
0.0065 mol × 342 g/mol = 2.223 g

4. Finally, convert the mass from grams (g) to milligrams (mg):
2.223 g × 1000 mg/g = 2223 mg

Therefore, the mass of the solute in 26.0 mL of 0.25 M sucrose solution is 2223 mg.

To calculate the mass of solute in a given volume of a solution, you can use the formula:

Mass of solute = Volume of solution × Concentration of solute

In this case, the given volume of the solution is 26.0 mL, and the concentration of the solute (sucrose) is 0.25 M. The molar mass of sucrose is 342 g/mol.

First, convert the volume from milliliters to liters. Since 1 L = 1000 mL, 26.0 mL is equal to 26.0/1000 = 0.026 L.

Now, calculate the mass of solute using the formula:

Mass of solute = 0.026 L × 0.25 mol/L × 342 g/mol

This can be simplified as:

Mass of solute = 0.026 L × 0.25 × 342 g

Mass of solute = 2.235 g

To convert grams to milligrams, you can multiply the value by 1000:

Mass of solute = 2.235 g × 1000 = 2235 mg

Therefore, the mass of solute in 26.0 mL of a 0.25 M sucrose solution is 2235 mg.

mols = M x L = ?

Then mols = grams/molar mass. You know mols and molar mass, solve for grams and convert to mg.
