A piece of black onyx was cut into a rectangular solid measuring 5.10 cm by 5.10 cm by 2.50 mm . What is the volume in cubic cen
Anika [276]

Answer:

Volume = 6.5025cm^3

Explanation:

Given

Initial Form: Onyx

Final Form: Rectangular Solid

Dimension of Solid = 5.10 cm by 5.10 cm by 2.50 mm

Required

Volume of the solid (in cm³)

The volume of a solid is calculated as thus;

Volume = Length * Width * Height

Assume the following;

Length = 5.10cm\\Width = 5.10cm\\Height = 2.50mm

The first thing to do is to convert the assumed height from mm to cm

Given that;

1mm = 0.1cm

This implies that

2.50mm = 2.50 * 0.1cm\\2.50mm = 0.25cm

Hence, the dimension of the solid in cm is:

Length = 5.10cm\\Width = 5.10cm\\Height = 0.25cm

The Volume is then calculated as;

Volume = 5.10cm* 5.10cm * 0.25cm

Volume = 6.5025cm^3

Hence, the volume of the rectangular solid is Volume = 6.5025cm^3

What is the volume, in l, of 0.682 moles of o'what 2 ​ gas having a temperature of 68.2 ºc and pressure of 5.82 atm?
klemol [59]

We will use Ideal gas equation. PV=nRT where P= pressure(in atm)=5.82atm V=Volume=? n= moles of gases=0.682 R = gas constant= 0.0821L atm / mol K T = temperature= 68.2 C= 68.2 + 273.15 = 341.35 K V= nRT/ P= 0.682 X 0.0821 X 341.35/ 5.82 V= 3.284 L.
