What is the molarity of a solution containing 8.9 g of NaOH in 550. mL of NaOH solution?
bulgar [2K]

Answer:

0.4 M

Explanation:

Molarity is defined as moles of solute, which in your case is sodium hydroxide,  

NaOH

, divided by liters of solution.

molarity

=

moles of solute

liters of solution

Notice that the problem provides you with the volume of the solution, but that the volume is expressed in milliliters,  

mL

.

Moreover, you don't have the number of moles of sodium hydroxide, you just have the mass in grams. So, your strategy here will be to

determine how many moles of sodium hydroxide you have in that many grams

convert the volume of the solution from milliliters to liters

So, to get the number of moles of solute, use sodium hydroxide's molar mass, which tells you what the mass of one mole of sodium hydroxide is.

7

g

⋅

1 mole NaOH

40.0

g

=

0.175 moles NaOH

The volume of the solution in liters will be

500

mL

⋅

1 L

1000

mL

=

0.5 L

Therefore, the molarity of the solution will be

c

=

n

V

c

=

0.175 moles

0.5 L

=

0.35 M

Rounded to one sig fig, the answer will be

c

=

0.4 M

Potential energy due to the position of an object above earth surface is called
KengaRu [80]

ANSWER:

Potential energy due to the position of an object above Earth's surface is called gravitational  potential energy.

EXPLANATION:

Gravitational energy is the potential energy compared with gravitational force, as work is  needed to further things against Earth’s gravity. The potential energy due to high positions is  called gravitational potential energy, and is evidenced by water in an elevated storage or kept  behind a dam. If an article falls from one point to different point inside a gravitational field, the  force of gravitation will do actual work on the object, and the gravitational potential energy will  decrease by the same amount.

How many protons neutrons and electrons does an electrically neutral atom of nickel have?
belka [17]
Since nickles atomicnumber is 28, that means it has 28 protons, which are positively charged. To cancel out the positive charge and make it nuetral, there isalso 28 electrons which are negatively charged.

Nickel has 31 neutrons because an atoms mass is the number of protons + neutrons. The # of protons is 28. The mass # is 59. So, there are 31 neutrons.

What happens when yeast is activated in two different ways?
skelet666 [1.2K]

Answer:

When the yeast get warm water and some food to eat (in the form of sugar), they will become active. And as they eat the sugar and break it down for food, they release carbon dioxide, which fills up the balloon. Yeast is actually a type of fungus related to mushrooms.

Hope it helps!!!
