Answer:
25 centigrams is equal to 2.5 grams.
150 hectometers are 10,000 centimeters.
Explanation:
10 centigrams is equal to 0.1 gram.
25 / 10 = 2.5
1 hectometer is equal to 10,000 centimeters.
150 x 10,0000 = 1500000
Answer:
7.64 Moles
Explanation:
As we know one mole of any substance contains 6.022 × 10²³ particles (atoms, ions, molecules or formula units). This number is also called as Avogadro's Number.
The relation between Moles, Number of Particles and Avogadro's Number is given as,
Number of Moles = Number of Particles ÷ 6.022 × 10²³
Putting values,
Number of Moles = 4.60 × 10²⁴ Particles ÷ 6.022 × 10²³
Number of Moles = 7.64 Moles
Answer:
We have the final answer as
<h2>0.68 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 40.8 g
volume = 60 mL
The density is
We have the final answer as
<h3>0.68 g/mL</h3>
Hope this helps you
Answer:
The temperature remains constant during change of state as during the process of changing state, only enough heat to change state is provided...These amounts can only change state and not temperature....This type of heat is known as <u>Latent heat</u>.
Latent is another word for hidden
