Answer:
They all have the same number of atoms
Explanation:
Which of the following has more atoms?
One mole of zinc
One mole of gold
One mole of silver
One mole of magnesium contians
O They all have the same number of atomst
a mole of anything contains Avogadros number of 6.022X10^23 things
which has the greatest number of thing? a dozen eggs, a dozen cookies, a dozen pizzas?
a dozen is a number means 12
a mole is a number that that means 6.022 X 10^23 you calculate the molar mass from the chemical formula, but every j mole contains 6.022X10^23
particles.
just like every dozen contains 12
so
They all have the same number of atoms
Answer:
a -4
b - 8
c - 5
d 2
Explanation:
Significant Figures: The number of digits used to express a measured or calculated quantity. By using significant figures, we can show how precise a number is. ... Accuracy: Refers to how closely individual measurements agree with the correct or true value.
To determine the formula units of the given compound, we need to convert from grams to moles first then convert it to formula units by using the Avogadro's number. We do as follows:
23.5 g <span>Sb2S3 ( 1 mol / 339.7 g ) ( 6.022 x 10^23 formula units / mol ) = 4.17x10^22 formula units </span><span>Sb2S3</span>
The difference between mineral and non-mineral nutrients is that one has minerals and the other doesn’t. For example, an apple and a table. An apple has nutrients, but a table doesn’t lol
