A sample of nitric acid contains 50 HNO3 molecules How many oxygen atoms are in this sample?
In each nitric acid molecule (HNO3), there is one oxygen atom. So, in a sample containing 50 HNO3 molecules, there would be 50 oxygen atoms.
Is oxygen gas heavy than air?
On average, oxygen (O2 which is 2 oxygen atoms) makes up about 20-21% of air. The bulk of the rest of it is Nitrogen (N2 which is 2 nitrogen atoms) (about 78%).Oxygen has a molecular weight of about 16 per atom. Nitrogen has a molecular weight of about 14 per atom. Pure Oxygen gas is thus heavier than "air."For example:Say you had a sample of air containing 8 Nitrogen atoms and 2 Oxygen atoms (80% N2, 20% O2). Based on atomic weight, it would come in at 150. (150 is calculated by multiplying the 8 nitrogen atoms by = 112, and then multiplying the 2 oxygen atoms by 16 = 32, and adding 112 and 32 together = 150).If you had the same amount of pure oxygen gas (O2), you would have 10 oxygen atoms times 16 = 160.So as a rough approximation, if the weights of oxygen gas = 160 and air = 150, air is approximately 93.75% the weigh of oxygen gas.. or in other words, "air" is approximately 6.25% lighter than pure oxygen gas.
How many unchanges atoms would remain after 3 half lives if the initial sample had 600 unchanged atoms?
After 3 half-lives, half of the original sample would remain unchanged. After the 1st half-life: 300 unchanged atoms. After the 2nd half-life: 150 unchanged atoms. After the 3rd half-life: 75 unchanged atoms would remain.
What is the ratio of carbon to hydrogen to oxigen?
In the universe, the ratio, by mass, is C : H : O = 1 : 150 : 2.
What is yardstick of atoms?
A yardstick is a unit of measurement equivalent to 36 inches. Atoms are incredibly small particles that make up matter. The comparison of the size of atoms to a yardstick emphasizes their minuscule scale.
