A helium balloon contains 0.40 g of helium. given the molecular weight of helium is 4.0 g/mol, how many moles of helium does it

Rasek [7]

Answer is 0.10 mol.

<em>Explanation;</em>

n = m/M

Where n is number of moles (mol), m is the mass of substance (g) and M is the molar mass of the substance (g/mol).

n = ?

m = 0.40 g

M = 4.0 g/mol

From substitution,

n = 0.40 g /4.0 g/mol

n = 0.10 mol

Hence, the balloon has 0.10 mol of He.

erastova [34]

Answer:

Grignard reagent is a chemical compound having a halogen group along with magnesium and organic group.

Explanation:

When cyclopentanol reacts with thiogyl chloride, it gives chlorocyclopentane as the product which on further reaction with magnesium metal gives Grigmard reagent as the main product.

A Grignard reagent is a chemical compound which have the chemical formula of R−Mg−X. Here, R is an organic group, Mg is magnesium and X is halogen. The organic group may be aryl or alkyl.

The reaction and the final product is given below at the attachment.
