Answer:

The answer is still 4.7

Explanation:

The first digit before a decimal (to the left) is called unit or one. However, the first digit after a decimal (to the right) is called tenth, and the one after that is called hundredth.

when rounding up, any digit greater than 4 will be rounded up to 1 and then added to the preceding number. But when the digit is less than 5, the number is rounded off to 0.

Hence, 4.7 is the same as 4.70 with the "7" being the tenth value and the "0" being the hundredth value. Hence, when 4.7 is rounded to the nearest tenth, it remains as 4.7 because its hundredth value is rounded off to "0" since it is less than "5".

Mrs. Borunda has a sample of oxygen gas that occupies a volume of 600 L at 400 atm pressure. What will the pressure be if she in
kotykmax [81]

Answer:

P₂ = 300 atm

Explanation:

Given that,

Initial volume, V₁ = 600 L

Initial pressure, P₁ = 400 atm

We need to find the pressure if the volume is 800 L.

We know that the relation between pressure and volume is given by :

P\propto \dfrac{1}{V}\\\\\dfrac{P_1}{P_2}=\dfrac{V_2}{V_1}\\\\P_2=\dfrac{P_1V_1}{V_2}\\\\P_2=\dfrac{600\times 400}{800}\\\\P_2=300\ atm

So, the new pressure is equal to 300 atm.

A chemist requires 0.802 mol Na2CO3 for a reaction. How many grams does this correspond to?
Komok [63]

Answer:

Ok:

Explanation:

So grams = mols*MolarMass. Here, MolarMass (MM) = 105.99g which can be found using the periodic table. mols is given to be 0.802. We can then plug in to get that it corresponds to 85.0g.
