To convert from formula devices to moles, you need to divide by Avogardo"s constant. And then remember the there will be 2 mole of Cl for every 1 mole the MgCl₂.1.81*10^24 formula systems MgCl₂ * (1 mole MgCl₂/6.022*10^23 formula systems MgCl₂) * (2 moles Cl/1 mole MgCl₂) = 6.01 mole ClThere room 6.01 moles of Cl atoms in 1.81*10^24 formula devices of MgCl₂.

You are watching: Calculate the number of moles of cl atoms in 1.81×1024 formula units of magnesium chloride, mgcl2.

If your front lawn is 16.0 feet large and 20.0 feet long, and each square foot of lawn accumulates 1250 new snowflakes every minu

couchsurfingcook.com:

36 kg/h

Explanation:

We begin calculating the total amount of square feet of the lawn v the rectangle area equation:

Area(rectangle)= lengthy x vast = 20 ft x 16 ft = 320 Now, because that every one of those 320 1250 brand-new snowflakes accumulates each minute, this way that means that in one minute us get:

# Snowflakes (min) = In a minute we have actually 400,000 snowflakes, then we must multiply that by the variety of minutes in one hour (60 min in an hour):

# Snowflakes (hour) = If each snowflake has actually a fixed of 1.50 mg (the average), then: In each kilogram there space 1000000 mg for this reason making this transformation:

36,000,000mg come kg ⇒ 4 0

What is the chemical surname of the compound represented by the formula Ni2O3? usage the list of polcouchsurfingcook.comtomic ions and also the regular tab
nikklg <1K>

couchsurfingcook.com:

nickel(III) oxide

Explanation:

In the polcouchsurfingcook.comtomic ions, the Oxides transporting a valence of 3 at formation of the compound together the valence electron switch,then the Oxides room tripled oxides hence likewise the oxide may be an oxynickel or oxonickelooxy.
