Well on a side note, a mole in chemistry is also the same as a Liter. A mole however, is the mass of an element,or compound. 1 mol of O would be 15.9994 grams/mol. It can also be represented as 6.022*10 to the 23 power. (1 mol of Carbon-12 atoms)

Consider the atom with the chemical symbol Ru.
Vinil7 [7]

Answer: 97

Explanation:

The element Ru is <u>Ruthenium</u> which has <u>44 protons</u>.

In this case, our atom is an isotope with <u>53 neutrons</u>.

With this information, we can use the mass number formula to find this atom's mass number.

mass number = protons + neutrons

mass number = <u>44 protons</u> + <u>53 neutrons</u>

mass number = <u>97</u>

HCI + NaOH --&gt; NaCl + H 20
Vikki [24]

Answer:

option D is correct

Explanation:

no of moles in 3 grams of HCL=3/36=0.08

if 1 mole of HCL require 1 mole of NaOH then 0.08 moles required 0.08 moles of NaOH

mass of 0.08 moles of NaOH=moles*molar mass=0.08*40=3.2 grams

so 3 grams are required in the reaction

state the formula for potassium hydroxide and explain, in terms of charges, how you formed the formula
Ganezh [65]

Potassium oxide is an ionic compound. The potassium has a charge of <span>K+</span> and oxygen has a charge of <span>O<span>2−</span></span>. We need 2 potassium ions to balance one oxide ion making the formula <span><span>K2</span>O</span>.

Potassium hydroxide is an ionic compound. The potassium has a charge of <span>K+</span> and hydroxide has a charge of <span>OH−</span>. We need 1 potassium ion to balance one hydroxide ion making the formula KOH.

<span><span>K2</span>O+<span> H2</span>O→KOH</span>

To balance the equation we place a coefficient of 2 in front of the potassium hydroxide.

<span><span>K2</span>O+<span>H2</span>O→2KOH</span>

I hope this was helpful.

Suppose that 2.14 grams of H2SO4 is mixed with enough water to make 225 mL of solution. Determine the Molarity (M) of the soluti
Alik [6]

Answer:

0.0970 M

Explanation:

Remember this equation:

mol/M x V

Convert it so that you can get M.

M=mol/V

Convert the 2.14 grams of H2SO4 into mols

=0.0218

Convert mL to L

225/1000

=0.225

Plug it in.

0.0218/0.225

=0.0970 M
