How many moles are there in 9g of Al show working?
9 grams aluminum (1 mole Al/26.98 grams) = 0.3 moles aluminum ==============
How one has more molecules 9g of water or9g of sugar?
Perhaps you mean: Does sugar have more atoms than water?In a certain fixed mass of sugar/water, there will be more molecules of water than of sugar since the molecular mass of sugar is higher than that of water. We follow the rule of Mass = Number of moles of a substance * Molecular mass of the substance.We rearrange this to form Number of moles = Mass / Molecular massTherefore, since the molecular mass of sugar is higher, the number of moles of sugar in a fixed mass of sugar is lower. The number of moles of sugar is directly proportional to the number of molecules of sugar, since we follow Avogadro's Law:1 mole = 6 * 10^23 molecules (constant value)However, if you meant to ask if sugar had more atoms than water, the answer is yes, it does. Sugar (presumably glucose) has the chemical formula of C6H12O6 and thus has 24 C, H and O atoms altogether. Water, with the formula H2O, has 3 atoms of H and O altogether.I hope this was helpful! :)
What is the mass of 3.5 x1022 molecules of co2?
To find the mass of 3.5 x 10^22 molecules of CO2, we need to multiply the number of molecules by the molar mass of CO2. The molar mass of CO2 is approximately 44 grams per mole. So, 3.5 x 10^22 molecules of CO2 would have a mass of approximately 1.54 x 10^25 grams.
How much DNA is inside a mango?
The number of protons in a mango depends on the mass of the mango, and then it depends on how accurate you want the answer. A proton is a hydrogen atom. As a first estimate, most of the mango is water. If it was ALL water then (as in 18g of water there is 2g of hydrogen and 16g of oxygen) then 1/9 of the mass would be hydrogen. 6 x 1023 = 600,000,000,000,000,000,000,000 . This very big :} number is called a mole and it's the number of protons in a gram, roughly. Each gram of hydrogen contains 6 x 1023 atoms, so 9g of mango with 1g of hydrogen contains 6 x 1023 protons. So, weigh your mango in grams, divide the weight by 9, and multiply that by 6 x 1023 to get the number of protons.
Which is bigger 2000 nanogram or 200 microgram?
2000 nanograms is equal to 2000 x 10-9g. Moving some zeroes, this equals 2 x 10-6g, or 2 micrograms. So 200 micrograms is larger.
How many moles are there in 9g of Al show working?
9 grams aluminum (1 mole Al/26.98 grams) = 0.3 moles aluminum ==============
What is 9g-g?

What is 49-9g?
49-9g = 40
What is 9g-142g?
9g-142g = -133
What is 12g plus 9g?
It is: 12g+9g = 21g
How do you factor 81g2 - 64?
(9g - 8)(9g + 8)

How many 240mg adds up to 9.0 grams?
249
How many carbs in a small bag of peanuts?
Planter bag of peanuts 2oz - 9g
What is the number of atoms of beryllium in 36.0 g of Be?
First work out the moles So do 36g / 80 (80 is bromine's relative atomic mass number) You have 0.45 M Then, do 0.45 * 6.02*10^23 You get 2.7*10^23, which is your answer
What is 9g minus 14 equals 2g?
