37.2 moles of hydrogen gas would have what mass? Your answer

Chemistry
1 answer:
raketka [301]2 years ago
5 0

Answer:

74.99g

Explanation:

Mass of a substance can be calculated by using the formula;

mole = mass ÷ molar mass

mass = molar mass × mole

According to this question, 37.2 moles of hydrogen gas is given.

Molar mass of hydrogen gas (H2) = 1.008(2) = 2.016g/mol

mass = 2.016 × 37.2

Mass of H2 = 74.995

Mass = 74.99g

The concentration of sugar in Coke is approximately 10%, or 100 ppt. If you drink
masya89 [10]

Answer:

35.5g of sugar

Explanation:

To solve this question we must assume the density of coke = Density of water = 1g/mL

Thus, in a single can of coke, the mass is 355g. Now, the 10% of this coke is sugar. That means the amount of sugar you are consuming is:

355g * (10/100) = 35.5g of sugar

<em>10/100 = 10%</em>

How many valence electrons are in the element gallium? explain how you determined the number.
Natasha2012 [34]

Answer:

three valence electrons

Explanation:

Gallium has three electrons in the outer energy level and therefore has three valence electrons. The identification of valence electrons is vital because the chemical behavior of an element is determined primarily by the arrangement of the electrons in the valence shell.

HCl (hydrochloric acid) is a strong acid; its ions completely dissociate when placed in solution. HF (hydrofluoric acid) is a we
FinnZ [79.3K]

Answer:

The stronger electrolyte is the HCl

Explanation:

Stronger electrolyte are the ones, that in water, completely dissociates.

HCl(aq) → H⁺(aq) + Cl⁻(aq)

HCl(aq) + H₂O(l) → H₃O⁺ (aq)  +  Cl⁻(aq)

Both are acids, they bring protons to medium but the hydrochloric completely dissociates.

HF (aq) + H₂O(l) ⇄  H₃O⁺(aq) +  F⁻(aq)           Ka

In the dissociation of weak electrolytes, they ionize but at the same time they bond again, so the reaction is always kept in equilibrium.
