How much space does a 246g box take up. Its density is listed at 3.2 g/cm3.
CaHeK987 [17]

Answer:

76.875 cm3

<h2>Explanation:</h2>

Since: Density = \frac{Mass}{volume\\}

Then: Volume = \frac{Mass}{Density\\}

The mass of the box = 246g

and the density = 3.2 g/cm3

Then: The volume = \frac{246}{3.2}

= 76.875 cm3

Compound A and Compound B are binary compounds containing only elements X and Y. Compound A contains 1.000 g of X for every 2.10
ycow [4]

Answer:

Explanation:

a) for 1.000 g X: 0.1621 g Y

ratio of mass of element Y = 2.100g : 0.1621g

= 1 : 0.07

b) 1.000 g X: 0.7391 g Y

ratio of mass of element Y = 2.100g : 0.7391g

= 1: 0.35 , = 20:7

c) 1.000 g X: 0.2579 g Y

ratio of mass of element Y = 2.100g : 0.2579g

= 1 : 0.12

d) 1.000 g X: 0.2376 g Y

ratio of mass of element Y = 2.100g : 0.2376g

= 1: 0.11

e) 1.000 g X: 0.2733 g Y

ratio of mass of element Y = 2.100g : 0.2733g

= 1 : 0.13

From the values obtained , the closest that is in compliance with the law f multiple proportions is option B
