I DONT NEED THE ANSWER JUST PLEASE TELL ME HOW TO DO THIS PLEASE, ITS DUE AT 12. BRAINLIEST. 15 POINTS! Copper (II) chloride has a molar mass of 134.452 g/mol. What is the mass of 2.17 moles?

292 g

Explanation:

Step 1: Given data

Step 2: Calculate the mass corresponding to 2.17 moles of copper (II) chloride

We will use the following expression.

m = n × M

m = 2.17 mol × 134.452 g/mol = 292 g

2.17 moles of copper (II) chloride weigh 292 g.

a is the answer to this question

explanation:

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
