Calcuate the number of<br> grams of solute in 453.9mL<br> of 0.237 M calcium acetate

AysviL [449]

The number of grams : 17.082 g

<h3>Further explanation</h3>

Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution

$\large {\boxed {\bold {M ~ = ~ \dfrac {n} {V}}}$

Where

M = Molarity

n = Number of moles of solute

V = Volume of solution

453.9 mL of 0.237 M calcium acetate

$\tt mol=M\times V=0.237\times 0.4539=0.108$

mass

MW Ca(C₂H₃OO)₂ : 158,17 g/mol

$\tt mass=mol\times MW\\\\mass=0.108\times 158.17=17.082~g$

Answer:

Formula for kPa to torr: For an approximate result, multiply the pressure value by 7.501. <em><u>84* 7.501</u></em>

Formula for kPa to atm: for an approximate result, divide the pressure value by 101. <em><u>84/101</u></em>

The energy produced by the snack in an experiment is calculated to be 41,800 J/g. What is the energy of the snack in Calories/

Goryan [66]

The energy of the snack in calories per gram is 9983.3 Calories/gram.

<h3>What is the energy of a snack?</h3>

The energy that is contained in a snack is obtained from a calorimeter when the snack is burnt in a calorimeter. The mass of the snack that is burnt is measured in terms of energy output of the calorimeter.

If 1 calorie = 4.18J

x calorie = 41,800 J

x = 41,800 J * 1 calorie/4.18J

x = 9983.3 Calories/gram
