Answer:
Number of carbon atoms present in the sample are 391.
Step-by-step explanation:
We are given that,
Ratio of carbon to hydrogen atoms = 1 : 4
It is given that a sample of methane consists of 1564 hydrogen atoms.
Let the carbon atoms in the sample = x
So, we have the relation,
i.e.
i.e.
i.e. x= 391
Hence, the number of carbon atoms present in the sample are 391.
Answer:
Largest possible mural that can be painted on the wall is 24 feet wide and 13.5 feet high.
Step-by-step explanation:
Design of a mural is 16 in. wide and 9 in. high.
Dimensions of the wall are 24 ft by 14 ft.
If we enlarge the size of the design along the width the wall, scale factor to be used,
Scale factor =
=
=
With the same scale factor, height of the design will be,
Width of the wall used =
= 13.5 ft
Therefore, largest possible mural that can be painted on the wall is 24 feet wide and 13.5 feet high.
