Answer:

Explanation:

In order to be able to say how many sig figs are used for the measurement 811.40 g, you need to know that

non-zero digits are always significanta trailing zero that follows a decimal point and a non-zero digit is always significant

In your case, the measurement

811.40

has four non-zero digits and one significant trailing zero.

8,1,1,4→ non-zero digits8,1,1,0→ significant trailing zero

Therefore, you can say that this measurement has five significant figures

811.40→ five significant figures

Boats typically have several metal fittings where ropes can be fastened. What is the name for these metal fittings?

nadezda [96]

The name for these metal fittings is cleats.
Cleats refer to the hooks on your boat and the dock where you can fasten a boat in order to keep it from flowing away while you're not using it. A keel is located under your boat and provides stability; a transom is the part of your boat on the stern where the motor is located; a tiller is a lever you use to turn your boat.

1. A light bulb is filled with 3.54 g of argon at 25 C and 725 mmHg. What is

Ugo [173]

Answer: The volume of given gas is 2.27 L.

Explanation:

Given: Mass = 3.54 g

Temperature = $25^{o}C$ = (25 + 273) K = 298 K

Pressure = 725 mm Hg (1 mm Hg = 0.00131579) = 0.95 atm

As moles is the mass of substance divided by its molar mass.

So, moles of argon (molar mass = 40 g/mol) is as follows.

$Moles = \frac{mass}{molar mass}\\= \frac{3.54 g}{40 g/mol}\\= 0.0885 mol$

Formula used to calculate the volume of given gas is as follows.

PV = nRT

where,

P = pressure

V = volume

n = no. of moles

R = gas constant = 0.0821 L atm/mol K

T = temperature

Substitute the values into above formula as follows.

$PV = nRT\\0.95 atm \times V = 0.0885 mol \times 0.0821 L atm/mol K \times 298 K\\V = 2.27 L$

Thus, we can conclude that the volume of given gas is 2.27 L.

PLZ HELP ME FAST I WILL GIVE BRAINLIST!! Two vehicles are traveling down the highway going 40 mph. Which has more kinetic energy

Mars2501 [29]

They actually have the same amount of kinetic energy but the bus I would say is more cuz it weighs more mass, more mass means the more energy it's going to need.
