Artyom0805 [142]

Each bracelet is $7 \frac{3}{4} inches$

Turn it into an improper fraction

Multiply 7 and 4 and add 3 which is over 4 which is $\frac{31}{4}$

Multiply by 4 | for each bracelet being made

$\frac{31}{4} * \frac{4}{1}$ $= \frac{124}{4}$

How many grams NaCl would you use to make a 4M solution in 100ml

MatroZZZ [7]

Answer:

Amount of NaCl = 23.376 gram

Step-by-step explanation:

Given:

Molarity = 4M

Volume of solution = 100 ml

Find:

Amount of NaCl

Computation:

Molar mass of Na = 22.99 g/mole

Molar mass of Cl = 35.45 g/mole

Molar mass of NaCl = 22.99 + 35.45

Molar mass of NaCl = 58.44 g/mole

Molarity = [moles of solute / volume of solute(ml)]1,000

4 = [moles of solute / 100]1000

Moles of solute = 0.4

moles of solute = Mass of solute / molar mass

0.4 = Amount of NaCl / 58.44

Amount of NaCl = 23.376 gram
