Answer: Approximately
============================================================
Explanation:
There are roughly 6.02 * 10^23 atoms in one mole of any element. So we have 6.02 * 10^23 atoms in one mole of nitrogen.
We can then do the following conversion:
Answer:
Density rectangular block = 7.47 (Approx) gm/cm³
Explanation:
Given:
Length = 8.335 cm
Width = 1.02 cm
Height = 0.982 cm
Mass = 62.3538 gm
Find:
Density rectangular block
Computation:
Volume of block = lbh
Volume of block = (8.335)(1.02)(0.982)
Volume of block = 8.3486 cm³
Density = Mass / Volume
Density rectangular block = 62.3538 / 8.3486
Density rectangular block = 7.47 (Approx) gm/cm³
Answer:
Drain Cleaner, soap, bleach
i think thats it, sorry if i got something wrong
The rule of solubility states that, like dissolves like. Water is a polar compound. Hence compound that is most polar, will dissolve maximum in water.
Among to available options, ethanol has maximum polarity. Hence, its solubility will be maximum in water.
Other solvents like benzene, toluene and carbon tetrachloride are non-polar in nature. Hence, they show poor solubility in water.
Answer:
The mass of helium in the balloon is 1.125 grams
Explanation:
Step 1: Data given
Volume of helium = 6.3 L
Molar mass of helium = 4.0 g/mol
Step 2: Calculate moles helium
1 mol gas = 22.4 L
6.3 L = 0.28125 moles
Step 3: Calculate mass of helium
Mass = moles helium * molar mass helium
Mass = 0.28125 * 4.0 g/mol
Mass = 1.125 grams
The mass of helium in the balloon is 1.125 grams
