Answer:

The correct answer is option C.

Explanation:

Alpha radiations are emitted by alpha particles imparts less amount of energy to the absorbing material.

Where as beta radiation by beta particles are more penetrating than the alpha particles and gamma rays are most penetrating radiations they can even penetrate through out a human body.

The order of penetration of these radiations from least to most is :

Alpha rays < Beta rays < gamma rays

Hence, the correct answer is option C.

If an experiment calls for 0.200mole acetic acid (Hc2H3O2)how many grams of glacial acetic acid do we need?

bija089 [108]

<h3>Molar mass:-</h3>

$\\ \sf\longmapsto HC_2H_3O_2$

$\\ \sf\longmapsto 1u+2(12u)+3(1u)+2(16u)$

$\\ \sf\longmapsto 1u+24u+3u+48u$

$\\ \sf\longmapsto 28u+48u$

$\\ \sf\longmapsto 76u$

$\\ \sf\longmapsto 76g/mol$

No of moles=0.2mol
Given mass=?

$\\ \sf\longmapsto No\:of\;moles=\dfrac{Given\:Mass}{Molar\:Mass}$

$\\ \sf\longmapsto 0.2=\dfrac{Given\:mass}{76}$

$\\ \sf\longmapsto Given\:Mass=0.2\times 76$

$\\ \sf\longmapsto Given\:Mass=1.52g$
