Answer: The thickness of metal sheet is 1.93 mm

Explanation:

The metals sheet is in the form of cuboid.

To calculate the width of the metal sheet for the given volume, we use the equation to calculate the volume of cuboid, which is:

$V=lbh$

where,

V = volume of metal sheet = $45.5cm^3$

l = length of metal sheet = 15.9 cm

b = width of metal sheet = 14.8 cm

h = height of metal sheet = ? cm

Putting values in above equation, we get:

$45.5cm^3=15.9\times 14.8\times h\\\\h=\frac{45.5}{15.9\times 14.8}=0.193cm$

Converting this thickness into millimeters, we use the conversion factor:

1 cm = 10 mm

So, $0.193cm\times \frac{10mm}{1cm}=1.93mm$

Hence, the thickness of metal sheet is 1.93 mm

Which of the following has the greatest mass? 1 mole of uranium (U) 1 mole of oxygen (O) 1 mole of sodium (Na) 1 mole of chlorin

Lelu [443]

To determine which has the greatest mass, we need to find out the molecular mass of each element:

Uranium (U) = 238 g/mol
Oxygen (O) = 16 g/mol
Sodium (Na) = 23 g/mol
Chlorine (Cl) = 35.45 g/mol

Therefore, if we have one mole of each element, the element with the greatest mass is 238 grams or Uranium.
