3.50L of 2.50M
solution contains
how many moles of
HCI?

Explanation:

Molarity = moles/ volume of solution in dm3 or L

given is Molarity 2.5 and volume 3.5 L

So, moles = molarity x volume in liter

= 2.5x 3.5

=8.75 moles

the atomic mass is the bottom number on the element.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
