A beaker in your laboratory drawer has an inside diameter of 6.8 cm and a height of 8.9 cm. Using the equation V= arh, calculate
olga_2 [115]

Answer:

323.22 ml

Explanation:

Given that :

Diameter, d = 6.8cm

Height, h = 8.9cm

V = arh

Recall :

Volume, V = πr²h

Radius, r = diameter / 2 = 6.8 / 2 = 3.4cm

V = π * 3.4^2 * 8.9

V = 323.21961 cm³

Recall:

1ml = 1cm³

Hence,

323.21961 cm³ = 323.21961 ml

Volume = 323.22 ml

Suppose you have 250g of gold(I) Chloride. How many grams of Gold do you have?
solniwko [45]

29.26 gram

Explanation:

No of molecules = no of mole × Avogadro's number

No of molecules = mass in gram/ molar mass × Avogadros number

Mass in gram =No of molecules×molar mass / Avogadros number

Mass in gram = 3.012 ×10^23 × 58.5/6.02×10^23

29.26 gram

6. STATEANSWERIN SIG FIGSOR g/cm3. What mass of silver in grams (g) would be required to cover a dimensions of 120.0 ft x 60.0 f
kogti [31]

Answer:

7.0643\times 10^8 grams of silver would be required.

Explanation:

Dimensions of silver mas :

Length = l =  120.0 ft

breadth = b = 60.0 ft

Height = h = 0.33 ft

Volume of silver mass ,V= l × b × h

V=120.0 ft\times 60.0ft\times 0.33 ft=2,376 ft^3=67,278,816 cm^3

1ft^3=28316.8 cm^3

Density of silver,d = 10.5 g/cm^3

Mass = Density\times Volume

m=10.5 g/cm^3\times 67,278,816 cm^3=7.0643\times 10^8 g

7.0643\times 10^8 grams of silver would be required.

Find the wavelength of the electromagnetic radiation with a frequency of 3.52x10^-22J PLEASE HELPPP!!!
LuckyWell [14K]

Answer:

λ   = 0.85×10³⁰ m

Explanation:

Given data:

Wavelength of radiation =  ?

Frequency of radiation = 3.52×10⁻²² Hz

Solution:

Formula:

c = f × λ

c = speed of wave = 3×10⁸ m/s

by putting values,

3×10⁸ m/s =  3.52×10⁻²² Hz × λ

λ  =  3×10⁸ m/s / 3.52×10⁻²² s⁻¹

λ   = 0.85×10³⁰ m
