Gasoline has a density of .74g/mL. How many milliliter if gasoline have a mass of 2.5kg?
nata0808 [166]

Answer: 3378.4mL

Explanation:

density of Gasoline = 0.74g/mL.

Volume of gasoline in milliliter = ?

mass of gasoline = 2.5kg

(Since density is in grams per millilitre, convert mass in kilograms to grams)

If 1kg = 1000grams

2.5kg = 2.5 x 1000 = 2500grams

Recall that density is obtained by dividing the mass of a substance by its volume

i.e Density = Mass / Volume

0.74g/mL = 2500grams/Volume

Volume = (2500 grams / 0.74g/mL)

Volume = 3378.4mL

Thus, the volume of gasoline is 3378.4mL

How is bacteria on mars counted as life but a heartbeat on earth not?
Sever21 [200]

Answer:

It is considered life, but that doesn’t have to do much with abortion.

We kill things all the time. Unless you are vegetarian, lots of animals are killed to give you meat. Even if you are, you’ll probably swat a mosquito that’s trying to bite you. And what about the bacteria inside your body that are constantly killed to keep you healthy?

The question is how much this life is worth. This becomes more a question of ethics, but I think we can all agree a human life is worth a lot. So killing humans is wrong. What about somewhat intelligent animals? Well, killing them just for the fun of it or because you can is wrong as well I think.Most people think that’s okay, although some people will disagree and become vegetarians.

Insect life is worth less, and killing an insect is seen by most people as okay as long as you have even a small reason for it (like being irritated by a buzzing fly).

And all the way on the bottom are bacteria. They are not conscious, even though alive.

Sorry about the first answer. I didn't look at the question carefully since I wasn't wearing my glasses.

If this doesn't help than I'm sorry.

Francium is the most reactive element in Group 1.
natali 33 [55]

Answer:

Francium is hypothesized to be the most reactive metal, but so little of it exists or can be synthesized, and the longest half-life of its most abundant isotope is 22.00 minutes, so that its reactivity cannot be determined experimentally.

Explanation:

Francium is an alkali metal in group 1/IA. All alkali metals have one valence electron. As you go down the group, the number of electron energy levels increases – lithium has two, sodium has three, etc..., as indicated by the period number. The result is that the outermost electron gets further from the nucleus. The attraction from the positive nucleus to the negative electron is less. This makes it easier to remove the electron and makes the atom more reactive.

Experimentally speaking, cesium (caesium) is the most reactive metal.
