Answer:
The pressure inside the container is 11 atm
Explanation:
We use the formula;
PV=nRT ---> P= nRT/V
P= 28 mol x 0,082 l atm/K mol x 215 K/45 L
<em>P=10,96977778 atm</em>
Mass number is
protons + nuetrons
So,
7 + 8 = 15
——-
Atomic number is the number of protons
so,
7
Energy given by carbohydrates present in one cup =
= 128 kcal
Energy given by proteins present in one cup = 
Energy given by fat in one cup = 
Total energy in one cup of cereal box = 128 kcal + 16 kcal + 18 kcal = 162 kcal
Energy present in two cups = [tex] 2 cups * \frac{162 kcal}{1 cup} *
= 324 kcal
Answer:
The mass of water is 36 g.
Explanation:
Mass of hydrogen = 4 g
Mass of water = ?
Solution:
First of all we will write the balance chemical equation:
2H₂ + O₂ → 2H₂O
Number of moles of hydrogen = mass / molar mass
Number of moles of hydrogen = 4 g/ 2 g/mol
Number of moles of hydrogen = 2 mol
Now we compare the moles of water with hydrogen from balance chemical equation.
H₂ : H₂O
2 : 2
Mass of water = moles × molar mass
Mass of water = 2 mol × 18 g/mol
Mass of water = 36 g
If the water oxygen is in excess than mass of water would be 36 g.
