ANS: density = 13.41 g/ml

Density (d) of a substance is the mass (m) occupied by it in a given volume (v).

Density = mass/volume

i.e. d = m/v

m = (d) v -----(1)

The given equation from the plot of weight vs volume is :

y = 13.41 x ----(2)

Based on equations (1) and (2) we can deduce that the density of the metal is 13.41 g/ml

Answer:

13.41 g/mL is the density of the metal.

Explanation:

y= 13.41\times x

Slope intercept form of line:

y = mx +c

y = y, x= x m = 13.41 and c = 0

y= 13.41x + 0

Where y and x parameter as are the weights in grams and volume in milliliter respectively.

\frac{Mass}{Voluime}=\frac{y}{x}=14.41 g/mL

13.41 g/mL is the density of the metal.

pshichka [43]
The general properties of Group 1 alkali metals are:
1. They form cations. 
2. They are highly reactive. 
3. They have a charge of +1.
4. They form ionic compounds. 
5. When their oxides or hydroxides are reacted in water, they form alkalis i.e. bases. 
6. They are usually soft in nature. 
7. They have low densities.

A piper delivers 9.98 g of water at 19 degrees Celsius. What does the pipet deliver
leva [86]

Answer:

the volume = 9.99 ml

Explanation:

in your Q we need to calculate the volume does the pipet deliver so , we are going to use this formula:

the volume = mass / density

here we need to know the density of water at a certain temperature 19 degrees Celsius ,so I used an external source   to get the density of water at 19 degrees Celsius because it is changing with different temperatures

where mass here = 9.98 g

and  the density of water at  temperature 19 degrees Celsius=  0.998405mL

-1

by substitution :

the volume = 9.98 g / 0.998405mL

-1

                   ≅ 9.996 ml = 10 ml

Where are the most active nonmetals located on the periodic table
AURORKA [14]

Answer:

The most active nonmetals belong to the halogen family, which sits to the left of the noble gases on the right side of the periodic table. The halogens are so reactive that they are never found in nature by themselves. The elements fluorine, chlorine, bromine, iodine and astatine make up the halogen family.
