Answer:
0.8g.
Explanation:
So, in this question we are to calculate for the actual yield of the product, Say C.
Thus, the equation for Determining the percentage yield is given as;
Percentage yield = actual yield/ theoretical yield × 100 ---------------------(1).
Therefore, from equation one above we can calculate the value for the percentage yield for product C.
A + B ==========================> C.
From the given value we have that, before the reaction there are 1.0 g of A and 7.0 g of B, after the reaction; we have 0 gram of A and 5.2 gram of B. That means that A is the limiting reactant. Thus, A Determines the reaction.
Hence, the mass of product C = 1 g = 0.1 × 10^1 grams.
Therefore, using the reaction (1) above;
Percentage yield = actual yield/ theoretical yield × 100.
80 =( actual yield / 0.1 × 10^1 grams ) × 100.
80 × 0.1 × 10^1 grams = 100 × actual yield.
Actual yield = 0.8 g.
a binary compound is a substance composed of exactly two different elements, which are substances that cannot be simplified further by chemical means.
Answer:
Four significant figures.
Explanation:
Hello,
In this case, considering that the measurement 16.08 L has four digits we must take into account that all are significant even the zero due to fact that is to the right of the first nonzero digit which is 1, therefore, the measurement has four significant figures.
Best regards.
1) The mass of 1 mole of virus is
2) There are 5.6 moles of viruses in an oil tanker
Explanation:
1)
One mole of a substance is the amount of that substance containing a number of particles equal to the Avogadro number:
This means that 1 mole of this virus should contain a number of virus particles equal to .
We know that the mass of 1 virus particle is
Therefore, the mass of 1 moles of viruses is equal to the mass of a single virus particle multiplied by the number of virus particles in one mole, :
2)
In this problem, we have that the mass of the oil tanker is
We also know that the mass of one mole of virus is
Therefore, we can find how many moles of viruses have a mass equal to the mass of the oil tanker by dividing the mass of the oil tanker by the mass of 1 mole of virus particles.
Mathematically, this is done by the following operation:
