nevsk [136]3 years ago
7 0

Answer:

(2H2O)=5.6mol

Explanation:

45.2g produce x mole of CH4

we are given the mass of methane

mass (CH4)=45.2g

molar mass (CH4) = 12+4 =16g/mol

Mole=<u>mass</u>

molar mass

mole=<u>45.2</u>

16

mole=2.8mol

therefore, if 45.2g produce 2.8mol as 1 mole of methane, the water produced is 2(2.8) we Are multiplying by 2 because the water is having 2 moles water mole is 5.6mol

Joanna fills a glass with 30 grams of water. She pours the water into a tray to make ice cubes. The tray has room to make 6 ice
alisha [4.7K]

Answer: Hence, the mass of each ice cube is 5 grams.

Explanation:

Mass of water in Glass : 30 grams

Rooms available for ice cubes in a tray: 6

Joanna carefully pours out the water from the glass into ice tray without spilling the any water, so, the mass of the water in glass will get equally divided into 6 rooms.

Mass of the water in one cube =\frac{30 g}{6}=5 grams

Hence, the mass of each ice cube is 5 grams.

How many Mg 2+ ions are present in 3.00 moles of MgCl2
Nostrana [21]
This is what I got hope this makes sense:There is 1 mol of Mg 2+ ions in one mole of MgCl2, we can get that from the formula.
Multiply 3.00 moles by 6.022x10^23 to get moles of MgCl2.
There are 6.022x10^23 ions in one mole of substance.
(3.00)(6.022x10^23)
=1.81x10^24 Mg 2+ ions
Hope it helps though
