Answer:
The density of a potato is 
Explanation:
Given that,
A potato that is too large to fit into a graduated cylinder.
Let us consider the mass of potato is M and volume of entire potato is V'.
The volume of water is V.
We know that,
Density :
The density is equal to the mass divided by volume.
In mathematically,
Where, m = mass
V = volume
We need to calculate the volume of potato
Using formula for volume
Where, V' = volume of potato
V''=Volume of combine water and potato
V = volume of water
We need to determine the density of a potato
Using formula of density
Put the value into the formula
Hence, The density of a potato is
Answer:
Percentage Yield = 56.9% (to 3 significant figures)
Explanation:
Firstly you need to calculate the amount of moles of Na used. Moles = Mass/Mr, so moles of Na = 1.72x10^-3/23. This gets you 7.47826087x10^-5 moles.
The mole ratio of Na:Na2O is 2:1 so the moles of Na2O will be the moles of Na divided by 2. This gets you 3.739130435x10^-5 moles.
Mass = Moles x Mr
The Mr of Na2O = 62
Mass = 3.739130435x10^-5 x 62 = 2.31826087x10^-3g
Percentage Yield = (Actual Yield / Theoretical Yield) x 100
Percentage Yield = (1.32x10^-3 / 2.31826087x10^-3) x 100
Percentage Yield = 56.93923481%
Percentage Yield = 56.9% (to 3 significant figures)
Answer:
Number one is the most acidic, the one in the middle is neutral, and number nine is alkaline.
You can't do that because it is impossible to convert a little thing into a big thing. You can convert meters to milliliters though.
Geothermal (volcanoes and heat sources from the earth) and solar
