the molar mass of l2 is 253.80g/mol and the molar mass of nl3 is the 394.71g/mol. how many moles of l2 will form 38.58 g of ni3

EastWind [94]

The moles of I2 that will form 38.58g of Ni3 is 0.147 moles

calculation
write the equation for reaction for formation of Ni3 from I2 and N2

that is 3I2 + N2 = 2NI3

find the moles of Ni3 formed = mass/molar mass

= 38.58g/ 394.71 g/mol = 0.098 moles

by use of mole ratio between I2 to NI3 which is 3 :2 the moles of I2

= 0.098 x3/2 = 0.147 moles

A laboratory assistant needs to prepare 217 mL of 0.246 M solution. How many grams of calcium chloride will she need

agasfer [191]

Answer:

5.92 g

Explanation:

Convert milliliters to liters.

217 mL = 0.217 L

Since molarity (M) is moles per liter(mol/L), multiply the molarity by the volume to find out how many moles you will need.

0.217 L × 0.246 M = 0.05338 mol

Now, convert the moles to grams using the molar mass. The molar mass of calcium chloride is 110.98 g/mol.

0.05338 mol × 110.98 g/mol = 5.924 g ≈ 5.92 g

You will need 5.92 g of calcium chloride.

A chiral amine a having the r configuration undergoes hofmann elimination to form an alkene b as the major product. b is oxidati

ozzi

Hoffman Product is always a less substituted alkene. In given scenario Structure A (Given Below) was taken as a starting chiral Amine. For the sake of elimination the amine was taken tertiary so that on methylation it becomes a good leaving group. This chiral amina (A) when treated with Methyl Iodide gives a quarternary amine which on treatment with Silver oxide yields less substituted Alkene (B) as shown Below.

Alkene B on Ozonolysis give two aldehydes i.e. Formaldehyde and Butyraldehyde.

If a substance has a large mass and a small volume how dense is it

Over [174]

Answer:

Very dense.

Explanation:

Conceptually, you are taking a large amount of atoms and putting them into a small container. This means the spaces between atoms has to be smaller and the substance is more dense. (see image)

Mathematically, the equation for density is mass divided by volume ( $Density=\frac{m}{v}$ ). If you divide a big number by a small number, you still have a pretty big number (ex 4/2=2 versus 6/1=6)
