The atomic mass would not change since the mass of an electron is negligible compared to the mass of protons and neutrons
The one with higher mass has a higher density because it fits more mass into the same amount of space (volume).
Answer:
148 grams of relative atomic mass
Explanation:
magnesium atomic mass : 24
nitrogen : 14
oxygen : 16
24 × 1
14 × 1 × 2
16 × 3 × 2
24 + 28 + 80 = 148 grams
Answer:
the oxidation state od boron in sodium boron hydride is (+3).
6.6ml will be the new volume if the pressure increases to 4 atm and the temperature are lowered to 200 K.
<h3>What is an ideal gas equation?</h3>
The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).
Given data:






Using equation:




Hence, 6.6ml will be the new volume if the pressure increases to 4 atm and the temperature are lowered to 200 K.
