a cell membrane is 70 angstrom (A)unit thick if angstrom unit is o.1nm what is the membrane thickness in a. meter b. micrometers
What is the answer
To convert the thickness of the cell membrane, which is given in angstrom (Å), to meters and micrometers, we can use the following conversion factors:
1 meter = 10^10 angstroms
1 micrometer = 10^4 angstroms
a. To convert the thickness to meters:
Membrane thickness in meters = 70 Å × (1 meter / 10^10 Å)
Note that 1 meter equals 10^10 angstroms.
Membrane thickness in meters = 70 × 1 / 10^10 meters
Simplifying, we get:
Membrane thickness in meters = 7 × 10^-9 meters
b. To convert the thickness to micrometers:
Membrane thickness in micrometers = 70 Å × (1 micrometer / 10^4 Å)
Note that 1 micrometer equals 10^4 angstroms.
Membrane thickness in micrometers = 70 × 1 / 10^4 micrometers
Simplifying, we get:
Membrane thickness in micrometers = 0.007 micrometers
To convert the thickness of the cell membrane from angstroms (Å) to other units like meters (m) and micrometers (μm), you need to use conversion factors.
1 Å = 0.1 nm
1 nm = 1 × 10^-9 m
1 m = 1 × 10^6 μm
a. To convert the membrane thickness from angstroms to meters:
Given: Membrane thickness = 70 Å
Conversion factor: 1 Å = 0.1 nm
1. Convert angstroms to nanometers:
70 Å × 0.1 nm/Å = 7 nm
2. Convert nanometers to meters:
7 nm × 1 × 10^-9 m/nm = 7 × 10^-9 m
Therefore, the membrane thickness is 7 × 10^-9 meters.
b. To convert the membrane thickness from angstroms to micrometers:
Given: Membrane thickness = 70 Å
Conversion factor: 1 Å = 0.1 nm
1 m = 1 × 10^6 μm
1. Convert angstroms to nanometers (same as step 1 above):
70 Å × 0.1 nm/Å = 7 nm
2. Convert nanometers to micrometers:
7 nm × 1 × 10^-3 μm/nm = 7 × 10^-3 μm
Therefore, the membrane thickness is 7 × 10^-3 micrometers.
