Great question! The subatomic particles that have most of the mass in the particle are the positive proton, and the neutral neutron. Therefore, protons and neutrons are the two subatomic particles have approximately 1 atomic mass unit each.
The SI base unit for mass is kilograms
Answer: kinetic, move faster, potential, change form
Explanation:
Answer:
The correct answer is 0.92 g
Explanation:
The density is defined as the mass per unit of volume:
Density= mass/volume
From the data provided:
volume= 5.4 L
density= 0.17 g/L
Thus, to calculate the mass of helium:
mass= density x volume = 0.17 g/L x 5.4 L= 0.918 g ≅ 0.92 g
It is logical to assume that they hydrogen ion concentration in an aqueous solution of a strong monoproctic acid equals the molarity of the acid because ions which are charged,for example ammonium ion (NH4+), which can be derived by the addition of a proton to a molecular base.
