Hello!
I'm going to have to infer that you meant "grams" and not "gallons" :-)
Anyways, to find the density, you need to the divide mass over volume (d = m/V).
Since we are given the volume being 15.0 mL, and the weight being 40.5 grams, we can find the density of the aluminum block.
40.5 grams / 15.0 mL = 2.7 g/mL
Therefore, the density of the aluminum block is 2.7 grams per milliliter.
Answer:
The probability her 4th child will be a girl is 0.5
Explanation:
during pregnancy or child birth, the gender of a baby is not affected by the gender of the previous baby in the womb. Rather it is determined by the type of chromosomes supplied by the father of the baby.
If X chromosomes are supplied, a girl will be born because the baby will have xx chromosomes. If Y chromosomes are supplied, the baby will have YY chromosomes which means that he is a boy.
Hence there are equal chances of the baby being a boy or a girl, each time a woman is pregnant. The probability of the baby being a boy or a girl is the same and it 0.5
Answer:
Fluids (air/water) either as water vapour or oxygen and carbon dioxide.
Explanation:
Heat transfer occurs through conduction, convection or radiation.
Many aties, this involves fluids whose molecules have been activated by heated by heat, moving from hotter to cooler regions, allowing for heating or cooling of the rooms.
Building materials have varying conductivity.
Answer: Baking soda
Explanation:
Sodium bicarbonate has a chemical formula of NaHCO3, it is a white precipitate formed when excess carbon dioxide is bubbled through a concentrated solution of sodium hydroxide.
It is used in cooking and serves as baking powder.
