What is the mass of 3.25 moles of sodium hydroxide (NaOH)?

1 mole is equal to 1 moles NaOH, or 39.99711 grams.

Explanation:

Hope this helps have a nice day :)

130 g

Explanation:

mol = mass/molar mass

Molar Mass of NaOH = 22.99 (Na) + 16 (O) + 1.008 (H) = 39.998

now your equation is:

3.25 = mass/39.998

multiply the molar mass to both sides to cancel it out on the right side

129.9935 = mass

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
