What is the approximate mass of 72 cm3 of silver, if the density is 10.5 g/cm3?
77julia77 [94]

Answer:

<h3>The answer is 756 g</h3>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

volume of silver = 72 cm³

density = 10.5 g/cm³

We have

mass = 10.5 × 72

We have the final answer as

<h3>756 g</h3>

Hope this helps you

Which equation can be used to convert from Celsius to Kelvin? O Celsius + 459.67 O (Celsius)x1.8+32 O (Celsius-32)x5/9 Celsius+2
Kaylis [27]

Answer:

Celsius +273.15

Explanation:

The two scales have the same size degree, but Kelvin is an absolute scale based on absolute zero while 0° in Celsius is based on the melting point of water. So, in order to convert from Celsius degrees to Kelvin we only need to add 273.15 to the given temperature:

K= °C + 273.15
