A 4.369 g sample of metal is placed in a flask. Water is added to the flask and the total volume in the flask is read to be 126.

4 ml. The mass of the water, flask, and metal is 268.5 g. If the mass of the flask is 139.3 g and the density of water is 1.000 g/mL, the density of the solid is ________ g/cm3.

Answer:

Density of the solid=2.78 g/cm^3

Explanation:

We are given that

Mass of sample of metal=4.369 g

Volume in the flask, V=126.4 ml

Mass of water, flask, and metal=268.5 g

Mass of flask=139.3 g

Density of water=1.000 g/mL

We have to find the density of the solid.

Mass of water=268.5-4.369-139.3=124.831 g

Volume of water=\frac{Mass\;of\;water}{density\;of\;water}

Volume of water=\frac{124.831}{1}=124.831 mL

Volume of solid=126.4 ml-124.831 mL

=1.569mL

Now,

Density of the solid=\frac{mass\;of\;solid}{volume\;of\;solid}

=\frac{4.369}{1.569}

=2.78g/mL

1mL=1 cubic cm

Therefore,

Density of the solid=2.78 g/cm^3

Sally has constructed a concentration cell to measure Ksp for MCln. She constructs the cell by adding 2 mL of 0.05 M M(NO3)n to
hram777 [196]

Answer:

0.1056 mole

Explanation:

As Sally knows that the charge on the metal ion is n = +2

$MCl_n=MCl_2$

In that compartment $[M^{n+}]=[m^{2+}]=8.279 \ M$

The volume of the $MCl_n$ taken in that compartment = 6.380 mL

So, the number of moles of $M^{2+} = 8.279 \times 6.380$

                                                      = 52.82 m mol

                                                      = 0.05280 mol

$MCl_n \rightarrow M^{n+}+nCl^-$

But n = 2

Therefore, moles of $Cl^-$ = 2 x moles of $M^{n+}$

                                       = 2 x 0.05282

                                       = 0.1056 mole

explain how both hydrogen and carbon have achieved stability by bonding with each other to form methane ​
Naya [18.7K]

A carbon iota can bond with four other iotas and is just like the four-hole wheel, whereas an oxygen iota, which can bond only to two, is just like the two-hole wheel.
