Approximately 3,000,000,000,000, or 3 trillion.
To answer precisely it depends on what the dust is composed of and how much the speck of dust really weighs. I assumed that the average molecular mass of dust was 150 grams/mole (about the weight of 10-12 carbon hydrocarbon), and that a speck of dust weighs 1 microgram (a millionth of a gram or 1 x 10-6 grams).
1 x 10-6 grams ÷ 150 grams/mole = 7 x 10-9 moles
7 x 10-9 moles * 6.02 x 1023 atoms/mole = 4 x 1015 or 4,000,000,000,000,000 or 4 quadrillion
This is approximate as I really don't know the weight of a speck of dust nor its molecular mass, but I think my estimate is reasonable, and if nothing else, I am underestimating the weight of a speck of dust.

Yes. The forces with which every speck of mass attracts every other speck of mass, just because they have mass, are called the forces of "gravitation", or simply 'gravity' by most folks.
no No the greater the mass of any object the greater the gravitational field. Everything down to the finest speck of dust has a gravitational field.
Could you name the following.
You dont measure dust and i dont why youde need to
Please help me get this speck of dust out of my eye.

A speck of dust is about as long as 1 millimeter; a speck of dust can be found in all houses.

In science, a "speck of dust" typically refers to a tiny particle of solid matter suspended in the air. These particles can vary in size and composition, ranging from microscopic particles like pollen or soot to larger particles like sand or debris. In scientific contexts, the term "speck of dust" is often used to describe these small particles when discussing their effects on air quality, atmospheric processes, or their potential impact on human health.
Mom cleaned so well there wasn't a speck of dust left in the house.

Gravity is a property of mass and space, and it exists everywhere in the universe. Every speck of mass in the universe attracts every other speck of mass in the universe with a gravitational force. Every star, planet, moon, asteroid, comet, meteorite, gas cloud, dust cloud, hairball, and raindrop "has gravity". No planet has no gravity
