Answer:
The density of a substance that has a mass of 75 g and a volume of 35 mL is 2.14
Explanation:
Density is a characteristic property of a substance that relates to the amount of mass it has per unit volume. In other words, density is the property that matter, whether solid, liquid or gas, has to compress into a given space (it measures the amount of mass in a given volume of a substance). It is calculated as the quotient between the mass of a body and the volume it occupies:
In this case, you know:
Replacing:
Solving:
<u><em>The density of a substance that has a mass of 75 g and a volume of 35 mL is 2.14 </em></u><u><em></em></u>
Answer:
4H2O(g)+3Fe(s)⟶Fe3O4(s)+4H2(g)
4H2O(g)+3Fe(s)⟶Fe3O4(s)+4H2(g)
Is there a question?
Explanation:
Answer:
Weight = 98 kg.m/s^2
= 98 N.
Explanation:
Weight of an object is defined as the product of mass of the object and the acceleration due to gravity acting on the object. Its unit is Newton which is denoted as N and is also equivalent to kg.m/s^2.
Mass of the object = 10 kg
Acceleration due to gravity, g = 9.8 m/s^2
Weight = m*g
= 10 kg * 9.8 m/s^2
= 98 kg.m/s^2
= 98 N
