Answer:
Explanation:
In multiplication and division problems, your answer can have no more significant figures than the number with the fewest significant figures.
(by my calculator)
There are three significant figures in 7.06 and two in 2.3.
You must round to 
significant figures and report the answer as 1.3 × 1.0⁷.
Answer:
(4) 230 kPa
Explanation:
The temperature is constant, so the only variables are pressure and volume.
We can use Boyle’s Law.
Divide both sides of the equation by 
.
Friction is the force that opposes motion between any surfaces that are in contact. There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces.
The molar mass of Naphthalene is 128g/mol
Therefore; a mass of 1.64 g of Naphthalene contains'
= 1.64g/128 g
= 0.0128 moles
But, from the Avogadro's law 1 mole of a substance contains 6.022 × 10^23 particles
Therefore 1 mole of Naphthalene contains 6.022×10^23 molecules
Hence; 0.0128 moles × 6.022 ×10^23 molecules
= 7.716 × 10^21 molecules
